I don't think I have clinical depression, I've seen clinical depression and I don't believe I have that. I think it's logical that someone who feels lonely and isolated, because they are, would be depressed as a result, I don't think that equates to actual depression.
And why are you lonely and isolated? Who, or what, is keeping you that way?
If I actually had someone to spend my time with and that I could see myself spending the rest of my life with, I'd be fine.
Neptune is currently transiting your seventh house, in its native Pisces. Being a Pisces sun, you're likely to be especially vulnerable to its effects. Neptune can bring wonderful dreams, creativity, and inspiration... and it can also bring extreme delusions. Some people fall very deeply in love during a Neptune seventh house transit... and if they're under the sway of a Neptune delusion, the person they fall for is not at all who they believe. There's a tendency to fixate on someone and build them up in your imagination to be who you want them to be, without getting to know who they really are.
You apparently have not fallen for any particular person. Instead, Neptune has given you an even more ethereal dream: if only you had the right person, all your problems would be magically solved. And that right person could appear any minute. All you have to do is wait.
But it doesn't work that way. Everyone in a happy relationship is in a happy relationship because they're working to maintain it, and so is their partner. They didn't get there by waiting around and wallowing in loneliness. They got there by being a whole and reasonably happy person who was ready to share their wholeness. Perhaps they wanted someone to love, but they didn't feel incomplete without it.
Relationships that start when one partner feels that they need the right person to make them happy are never happy relationships. No one person can make anyone thoroughly happy. Happiness depends on many factors. If you do meet someone special when you feel like this, you'll put such heavy pressure on them to make you happy that they'll want to run away from you. Or they'll be as insecure as you are and drag you down further. Or they'll turn out not to be who you think they are, which will be a very rude awakening.
But certainly no one would be happy in a situation where they're alone.
About five years ago, there was a girl who sailed around the world alone. She didn't see or speak to anyone for months at a time. Do you think she was unhappy?
Ever heard of John Muir? He spend many months of his life, years if you look at it cumulatively, wandering around the Sierra Nevada alone, and he wrote very joyful essays about it. Do you think he was unhappy?
People who have depression don't have a reason, they have an illness regardless of how well their life is. A person who would be relaxed, happy, and carefree in my situation would be the one who has something wrong with them (no offense to anyone with a mental illness, I don't mean for that to sound insulting in any way).
From how you've described your external situation, there's nothing in it to make you unhappy. The only thing you're complaining about is lack of a social life, and you haven't said that people are putting you down or refusing to socialize with you. Some people do socialize with you. Maybe only casually, but they are socializing with you.
Unless there are other details that you haven't shared with us, this isn't exactly situational. It's coming from within. It's your internal situation that's making you unhappy, not your external situation. Your lack of a social life is just a reflection of that.
Suppose you're out for a walk and you meet two dogs. One of them comes up to you, tail wagging, puts itself right under your hands, and insists that you pet it. The other growls at you, maybe with a bit of wagging tail as well, but still growls. Which dog would you pet? Which one would you hug or play with?
When you're so down on yourself, the vibes you put out are like the growling dog. The people you see other people flocking to are like the friendly, tail wagging dog. I'm not getting that from your chart, I'm getting that from a knowledge of human nature and the vibes people put out, although you have a chart factor that probably exacerbates it:
Pluto squares your ascendant almost perfectly. People with Pluto square the ascendant are bound to be perceived as scary by at least some people, and if in a bad emotional state, that "scary" perception may be held by everyone. It's not an absolute given, and if someone with Pluto square the ascendant is in a good emotional state, the "scariness" doesn't keep them from having friends, it's more likely to become a joke between friends. I have Pluto square my ascendant, and there are some people... particularly men... who react like I'm the Wicked Witch or something, even if they barely know me. It happened the most often when I was in my late teens to mid twenties.
I know my chart makes me prone to thinking and being certain ways because I know what a chart is, my question is will this ever change?
It can... if you participate in the change. Birth charts don't say what will happen. They show you what areas of your life are likely to be challenged, and they show you ways that you can change if you have a mind to, but they leave it up to you to decide how to carry it out.
Of all the things my chart says, does it ever indicate marriage and children? Approximately what age?
Birth charts never show that. Some astrologers say this planet or sign or aspect in your seventh house shows marriage or no marriage or late marriage, and this planet or aspect in your fifth, etc. shows children or no children or difficulty having children, but those predictions are wrong more often than not.
The 'cure' for my problem (feeling alone) is meeting a person I like and then can make a connection with. I can control myself and what I do, but I can't make another person talk to me and want to get to know me...so the answer isn't simply within me.
You're partly right. The answer is not simply within you. When you're that deeply into a bad emotional state, there's no getting out of it without help. It's true that another person could help, but not true that the right person to help would be a friend or lover. What you're dealing with is way too heavy a burden for a friend or lover to relieve you of. However, a therapist could.
