Probably shouldn't be posting this and will really regret it.
Is it ever okay to wash your hands of someone you're supposed to love and support? If they absolutely refuse point-blank to get help for their problems - if they've told you over and over again that there's no hope for them and all offers of help/advice/support/therapy are useless - even so, it's wrong to take them at their word isn't it? And even if their problems are taking over your life, and messing with your own mental health, if you're still stronger and healthier than them and you love them and want to them to get better, you have to hang in there don't you?
I am so close to walking out on a situation because the person who needs the help just won't take it, not from me, not from professionals, not from anyone. What to do?
