I can't tell you what I did as I'm in a very similar situation and also looking for answers.

I am spending part of my time at my mothers house for the summer. I was working but lost my job. I go back to university in September. I have lived a quiet isolated life with no real best friends, just acquaintances here and there. I did however have one true loving relationship in my life. One true passionate love. But now she is gone. Like you I'm not unattractive or anything like that, in fact just the opposite. But for some reason I never sought out a relationship. Anxiety issues mostly. Fortunately I did find love anyway. Or perhaps it found me. I guess my only advice to you is that sometimes we find what we're looking for when we least expect it. You never know what or who is around the corner so you can never give up.

I too was terminated by my therapist. I highly doubt for the same reasons as you but it ended nevertheless.

I too worry that my personality doesn't fit with the field I chose to study. I'm working towards a degree in psychology. But I do not know if I will be able to find employment due to my own psychological issues.

You are not alone.
