Struggling with Anorexia and Self-Harm: Stop Invalidating My Feelings

I've been dealing with my ED for such a long time, without any support. Ppl are always telling me to quit self-diagnosing, but I'm not. I've seen multiple doctors for my anorexia. Ppl are always telling me to quit lying abt being anorexic, just bc they noticed that I've gained weight and that I eat. Just bc u see me gaining weight and eating, doesn't mean that I'm not anorexia. It doesn't mean that I'm lying to other ppl so they pity me. It means that I'm silently struggling alone, and trying to hide it from others, so ppl quit saying that I'm doing it for attention. Same w/ my sh. Ppl always are saying that I'm doing it for attention, but I'm not. If I was doing for attention, I wouldn't be trying to hide it from u. And even if someone is doing sh for attention, they still obviously need help, whether u or them realize it. So, stop invalidating others feelings and problems. It gets tiring for the ppl who have these problems. I'm abt ready to give up again. I don't know how much longer I can take this..
