Struggling to Explain My Mental Illness to Family

I find that if people aren't actively trying to understand you, they don't want to, and they're not going to. My family actually used my diagnosis and that fact that I went to therapy as their "proof" I'm "the problem." I bought books on it, shared tons of stuff about it from support groups on Facebook, tried to share what I learned in therapy; All to just apathy or ridicule. If they are at all dismissive like that, I would say seek like-minded friends in support groups, and go to therapy if you can. People that make you feel this way are being detrimental to your mental health, and if you explain it to them like that and they still can't respect that and try to be more understanding, they will just continue to hold you back/keep you down. I sincerely hope your situation isn't like mine and maybe it will open their eyes to how important them understanding is, especially to people with BPD
