I have a sibling that I used to be very close to and still care about, but it's been several years since they cut off contact with me after their therapist advised them to because of "codependency issues." Otherwise, I have no other immediate family alive. I wasn't particularly close with most of my relatives, but both sides (mother/father) cut me out several years ago. Father's side resulted from infighting after my abusive grandfather died and left a hefty chunk of inheritance without any will in place. I didn't even find out about my grandfather's death until the ugly aftermath - apparently, I was legally entitled to the largest share, so was kept in the dark and finally cut out (disowned almost?) after the dust settled. I only found out because an aunt who I got along well took it upon herself to contact me one last time informing me of the final decision along with a bit little bit of cash as an "apology." I've never heard from them again, even the aunt I was close with. Mother's side - my mother was never treated for mental illness, and once full on schizophrenia set in to the point of no return she basically spent the rest of her life on the run from imaginary enemies, psych wards (with every visit leaving her worse off), and destroying the lives of those around her. Once she was done ravaging my and my sibling's life, she moved on to her siblings and their families. They would plead with me to take her in because they didn't want to deal with her while refusing my advice to contact authorities/mental health professionals. After a few years they decided I had neglected my duties to my mother (it's a cultural thing having to do with my ethnic origins), and unleashed all their anger on me and cut me off. As for my mother, she passed recently in an ugly way, homeless. Aside from family, I actually had quite a few real life friends from school and work, but we grew apart and it's been 4(?) years since the last time I was able to contact any friend and have a conversation. I had thought for sure I had close friends, but now I question whether we were really close after 4 years of isolation. I've also attended quite a few support groups and met with countless mental health professionals in the past, but stopped after 2 decades worth of trying seemed to yield very little (if no) results (and sometimes resulted in quite bad advice).
