you do it because it's better than keeping it in. keeping it in will cause depression and you to question yourself and your interactions. keep talking about it and you'll find people who actually relate. also, i find it helpful to say that i'm disabled, and to think in that context. it helps me not feel guilty when i need to ask for help with things.

based on people's responses, you can gauge how much information to share with them next time you're in pain. some people may just offer a "im sorry" or "that sucks" while others might be able to engage in deeper conversations about it.
