This is literally me tbh. I also likely have bpd so that probably does not help, but I have started cutting off any friends I have, irl or online, cause I feel like they constantly laugh at my hideous appearance. It is really driving me crazy, cause some days I feel really pretty and other times I feel hideous and I do not even truly know how I look like and it feels completely sickening. Sometimes someone will tell me something nice like "oh anon, you could definitely be a model if you took better care of yourself" and I feel great, but then it goes away like a few hours later and I need more re-assurance and then sometimes someone will say something like "anon, you look like a female Jesus" (actual comment I got) and I get so upset I do not go outside or talk to anyone for days. I really wish I knew how to cope with this but I have not really found anything that works consistently, sometimes I can "overpower" a bad mood but then it comes back in like two days and I just give up.
