Feeling alone advice!

Hi. I would like to give you a little bit of context. I am form latin américa, I am around 30YO, female. And I'm writing in English and giving you approximate information so I remain anonymous. Lately in my life I discovered there is a pattern in my way of relation with other persons: friends, colleagues and partners. I always end up alone. In my job just happened that the people that say "we are friends" finally are not talking to me anymore, and I tried to ask them what I did wrong but I just received a vague answer that they were busy and the other one didn't even answer. And I am not mad about that as those persons were never really my friends as they seem a little superficial to me, so I do not feel upset about that but about the fact that this is repeating. In my previous jobs and collègue I always ended up alone, minimum to no friends, and I always wondered what am I doing wrong. I know some people may not like me or I am not compatible, but it is weird to se it repeating so much. My partners in the other hand are always selfish, immature, and at the end, again, leave me alone. Little to no support emotionally or even physically speaking (like company). I've been going to the psychologist for over 4-5 years and I am kinda tired of not knowing what is going on. I think I know my patterns and my best bet till now is that whn I was a teenager and as young adult I was harsh on people, but that was +10 years ago and I honestly think I've changed (even one of the persons in my job said that to me, as she has seen me in collègue before and she always thought I looked uninterested and harsh in socialization). Then I do not know where to look for my people or what else to analyze about myself. Also other friends that I talked about this and feeling lonely - as I have few friends and spend my weekends with my little family only - just tell me that I just need to change friends and that I complain about this too much. I would like to isolate from people now, because: 1. It is proly that being around me is difficult and Idk how to change it and 2. Being around people is difficult for me, so it is better for all of us if I just remain alone. But I am also scared about that as I was diagnosed with depression 4 years ago, took medication and was finally discharged of treatment as everything came up well. I do not want to be depressed again, and I know depression and isolation are very good friends. So please advice me on what to do, what other attitudes I should have (maybe my dark humor is something I have to abandon) or what places would you go. Pls consider I am from latin america. Btw, English is not my mother language so let me know if I made any mistakes.
