Q: I have bad anxiety and I put a blog explaining why anxiety made me leave school so that people wouldn't ask questions, a few weeks later a guy I've been friends with for years but grown apart from came to me saying he has depression. I didn't think anything of it until he came to me everyday saying he wanted to kill himself, and then came to me with a knife saying he didn't dare cut himself so wanted me to do it, and asked for tips on the best way to do it. Ever since then I haven't wasted my breath on him, just listened. Nothing he says ever adds up: he was taking 20 anti-depressants a day, he said his doctor diagnosed him with depression and then told him that he was wrong and then re-diagnosed him and then told him it wasn't, he said that his counsellor said that it sounds like has bipolar, depression, Alzheimer's, Parkinson's disease and anxiety. This all seems like such rubbish, and I don't want to waste my time on an attention seeker, because it made my anxiety worse at one point that I couldn't help him. He constantly says that he would rather have social anxiety, agoraphobia and panic attacks like me than have bipolar like him, saying that I have it easier than him.
Is there a way I can find out if he is lying or attention seeking? If I stop going out for walks with him then I'll never leave my house, making me worse. I don't know what to do.
