I'm upset all the time I self harm, I cry all the time, have panick attacks and suicidal thoughts, and I don't like being outside, I have no friends really , I know this sounds stupid but I think I would like to be sectioned to get away from everything to sort myself out, would people do this? I don't want to be in school but I want an education is there anyway the could do it at home legally so I don't have to go out? Please don't be horrible I made an account especially to ask this btw live in uk
