Based on looking at your chart, I think these relationship issues are all about your current life. Maybe there are also karmic elements involved, but that may be a subject for another post, since what I have to say here could be lengthy....In addition, I have the absolute worst luck at dating and relationships. I can never seem to form a long-term partnership because I "come on too strong" and feel very deeply, which scares a lot of people away. That's the main reason. Other times, people would give the most ludicrous and irrational excuses not to pursue me after the first date (which usually goes very well!), most likely because they feel so insecure about themselves when they come into contact with my energy. Every time I get rejected or tossed aside for no logical reason, I then lash out at them with most hateful and hurtful words nobody has ever heard someone say to them before. I do that in order to give a "crushing blow"...to make believe that they're dead to me so I can move on.
Because of these irrational excuses people tend to give, I'm really beginning to think that these failed dating attempts are karmic in nature, due to a past life of committing suicide.
Only difference here is, you have more of an air sign and perhaps slightly less of an earth emphasis than I do, but we both have fire emphasized, and we both have fire sign grand trines. Yours links the moon, Neptune, and your Venus/Mars conjunction. Since you have Mars and Aries involved in your trine, plus the very independent Capricorn rising and Saturn conjunct the MC, it's no wonder that you come on strong, and no wonder that you have a very fiery and militant way of reacting and covering up your emotions. (I tend to coldly withdraw instead when I feel hurt by someone, maybe a difference in our Saturn placements--mine is in the seventh house, in Cancer.)Saturn is where we feel our separateness from life most acutely, but this separateness is really a figment of the imagination, and Saturn's ultimate purpose is to show us the futility of trying to compensate for this sense of separateness. Since you have Capricorn rising, the Saturnian process (of realising the futility of seeking worldly compensations for an illusory sense of separateness) has great bearing on your ability to emerge spontaneously into life moment by moment. The way that you engage with the world around you will be inhibited by Saturn problems (such as self-doubt, frustration and over-compensatory ambitions an cynicism) to the extent that you still believe yourself to be separate from life, and thus inherently insufficient.
Looking more closely at Saturn's placement in your chart, it is the only planet in a water sign. So the sense of separateness arises on the level of feeling. The process described above will draw you into water-type insecurities. You won't necessarily be especially aware of these insecurities, because the fire earth emphasis in your chart confers on you the luxury of generally avoiding the fact that feeling intimacy is very important to you deep down. But they are there waiting to be looked at.
Speaking of medical school, I wonder if there's an astrological correlation to that profession in my chart. I think there is. I was a health care major in college back in the early 2000s, then my college messed up a few things that tampered with me finding a suitable job. So after 8 years since I graduated, I'm deciding to fix the mistakes my old college made by doing the sciences over again (the vast majority of them, at least) and pursuing medical school. At this point, I see no other option.
All of that is also indicated in your chart. Looking over my own post, I realize that I didn't mention research as a distinct possibility. It was in my mind, but I was already being so wordy that I forgot to include it. Research is well indicated by your placements, and it would certainly fulfill those Gemini and Scorpio imperatives. I really appreciate your insights on Uranus and Pluto... it helps me understand my own chart, too. I'm also of the Pluto in Libra generation, and I'd just been trying to figure out what that means for me. Makes lots of sense. And while my Uranus is in Libra, it's at the cusp of Scorpio, so again, we're birth chart siblings!Don't read into the whole "going to medical school" vs. "wanting to be a doctor" thing. By going to medical school, that implies that I want to practice medicine. I have my own reasons for doing so, which include playing a crucial role in the treatment of others, dealing with objective facts and bringing order to chaos, and unveiling the truth. Those are my needs that I have a strong desire to fulfill in this life.
My top 2 specialties are pathology and psychiatry because they are both extremely investigative. I was initially trained in pathology, since that's my undergraduate degree and I'm more familiar with that branch of medicine. It's more of a "behind the scenes" field that doesn't involve a lot of patient contact (which I don't mind at all, really). Intense lab work, diagnosing various diseases, and the like are just fine with me. Again, I'd be playing a crucial role in the treatment of patients. Pathologists are "the doctor's doctor", really.
If I want to specialize even further in pathology, I would go into forensic medicine (medical examiner). Talk about a variety of cases and investigation galore! It's never a dull moment with that (which actually might appeal to my Gemini 6th House). Rather than see Gemini as teacher, you can also see it as requiring a lot of variety and mental-type tasks in your job (which I absolutely do need). With Uranus ruling my 2nd house, my source of money indicates something "unusual". I think my income predominantly coming from dead bodies is highly unusual and taboo. Then you have the Scorpio MC...Scorpio is all about death. So that's pathology right there....
Psychiatry is another area I'm looking into. Again, that deals with investigation...this time, of the human psyche: bringing events, concepts, etc. into the light in order to effect a cure. Whereas pathology deals with the body, psychiatry is the best counterpart to deal with the mind. Mind and body....there it is. Gemini 6th house (working with the mind), Uranus ruling the 2nd house (dealing with unconventional people, nutjobs, Uranus being the higher octave of Mercury the mind), Scorpio 10th house (investigating, medicine, Pluto in Libra symbolizing transformation on the individual one-on-one level like what happens in therapy). Seems like both pathology and psychiatry are my best medical specialties to pursue. Either way, the central theme for both is to get to the heart of the matter and expose the truth for the greater good (i.e. effective treatment and well-being of the public through service). There it is.
