I'm sorry to hear about your troubles.
You have several placements indication delays and confusion regarding your career.
Before I start, I'd like to know why do you believe that you want to be a diplomat? It's not something people usually decide to be early on, especially not children
I've always wanted to work globally, such as working for a global organization. I never want to just work in my home country. I love the diverse people and cultures of the world. Maybe it's more like working for a global organization for a humanitarian cause? I think it's such a great life to have to travel around the world and advocate for something good for everyone in the world.
Sun in 10th opposition Saturn in 4th bring about delays in your career. Not to mention that you have Chiron in 10th indicating some sort of obstacles in defining your dream job due to some deep "wound" that Chiron symbolizes, maybe connected to too high expectations from your father figure in your childhood. (sometimes it works in reverse, kids whose parents are constantly disappointed by them and have given up on them, dream of achieving greatness to prove them wrong).
Oh gosh, it's really because of the opposition between my Saturn and Sun.... I think I can totally confirm this reading, because everything you said is very true. Although as I've said I love working internationally, I swung between a lawyer, teacher, professor, and diplomat. All of these seemed like such wonderful careers to me, but there are also reasons I can't follow them. For instance, I decided not to become a teacher because I believed I'm not good with kids at all. I decided not to become a professor because it would take me to long to study instead of making money for myself and my family.
About the father part, it probably works in reverse for me. My father was very young when he had me and my siblings. He was barely home and responsible for bringing us up. I've had this idea since I was a child that I'll never become like him. I will economically support my family, but I can't even do that now!
Your 4th house (family, home) is full of pretty heavy planets and I'd say that here's where the confusion and restrictions come from. You may have adopted certain patterns and behaviors (ideas, principles) early on and without questioning them.
I'm pretty sure it's actually happening, but I can't identify which ones from my family have grown on me.
Being a diplomat involves contacts, communication with foreigners, so I'd say that you have aspects for that - foreign languages and communication with foreigners but I cannot say if it is enough. Your lord of the 10th - the Moon is in the 3rd house and your 9th house of higher education is in Gemini (languages, communication).
Do you think I can a better career choice? With this kind of bad situation in my life, tbh, I don't know what my strengths are. I don't really have passion for most things anymore.
Your 10th in Cancer can speak of somehow continuing a family business (so if your parents were diplomats, that would be it
, or dealing with homes, children, nourishment.... What further strengthens this idea is the fact that the lord of your 6th house is in the 4th (naturally Cancer) which deals with family, home.
My father, from what I know, has always been jobless, and my mom works menial jobs. Sometimes i wonder if my situation comes as an inheritance from my parents. Now it seems like it can come from my father
But, the most important thing for you is to dig dip. Understand WHY you have this desire to be a diplomat and does it really suit you.
What have you done so far in that direction?
Have you done some internships in international organizations?
Have you checked out what UN policies are for accepting interpreters, translators (this could be your way in)?
I don't mean to sound harsh, but being diplomat is unfortunately reserved for a very small circle of usually very well connected people.
You're Sun is in the 10th so you can be ambitious or pretentious. Evaluate your options. Be realistic. Don't let your ego get the better of you.
I have plans for all these things, but the lack of job has been stalling all those. I want to make money on my own, use it to attend a school of international studies, and join activities of the international organization. I can't even make the first step done. That frustrates me, and I'm now at a very big loss. I'll re-evaluate myself when I have the salaries coming in, I think, but now it's all very dark in my head.
