[Content Warning: Descriptions of mental illness, past suicidality, heavily manipulative behavior motivated by fear and mental illness]
I have some sort of personality disorder (either Dependent, Borderline, or -NOS) and, well, I have ridiculous abandonment issues. I've always been incredibly incredibly attached to close friends, but as I've gotten older, I've been in so, so much pain around the idea that they'll leave me for romantic partners. I also do have the need, divorced from romance, to be someone's "number one". While I'm quite stable and doing okay now (thanks to a wonderful qpp, some vaguely decent meds, and a truly incredible therapist), I have in the past threatened to kill myself over my two closest friends leaving me (with one, it was "if you kill yourself I'll kill myself too because I can't live without you", and with one it was "if you leave me for your girlfriend I'll kill myself because I can't live without you"; while I am no longer friends with the first, neither are dead, and neither am I, so...that's a win, I guess?). I'm no longer suicidal at all, so no worries there, but I'm still incredibly, paralyzingly terrified of being left alone. Add this to the fact that I have more mental illnesses than I do self-care skills (can't consistently: cook, wash myself, do work, look normal/presentable; can consistently: have panic attacks, psychotic breaks, depressive episodes) and that I don't know if I'll ever really be able to achieve independence, and so my dependence on others gets even more intense, which tends to drive them away more (the stronger I feel about someone, the weirder and creepier it makes me--unless it's romantic, then it's "cute"!). Right now I have a qpp who I hope to live with in the future, and she respects me as a possible life partner, but she has a girlfriend and I can't shake that doubt that she'll leave me like most people leave their high school friends. I have a strong need for human connection, despite being introverted, and I need to be taken care of (there's that DPD again!), so I really do want/need some sort of living situation with friends when I grow up. I do also have a sex drive, although I've pretty much resigned myself to either being celibate or having one-night stands occasionally. Although the "poor self-care skills" makes me kind of an undesirable sexual partner, so the celibacy is probably more realistic I also panic when people have crushes on me, because it is a lot of pressure that I know I, as an unstable aromantic, cannot really live up to, and crushes aren't something I can really avoid, especially if I want to be live with, be friends with and/or have sex with other people, something that the majority of allos have trouble maintaining as "platonic". I like to hope that I'll be recovered enough that I won't need these things, but that's.. well, it's not exactly realistic, even if worrying about the alternative is really only making me worse at this point.
tldr i have a lot of fears about growing up aromantic and mentally ill, mostly about being alone, abandoned, seen as second-best, and being unable to take care of myself, and they're all really big and i don't really know how to deal with them.
