My son has been manic and delusional since November and is not medicated- refuses actually. He has decided that he is buying a throughly unpractical car. He got the loan- I don’t know how- we told him it’s foolish but it’s his life — we can’t stop him. We keep trying to delay but apart from keeping him hostage he’s going to do what he wants. He’s 28 by the way. What more can we do???
