Mental health or none. FML?:/?

Yahoo answers isn't the place for the kind of help you need. Please go to see someone like your school counsellor or just seek any kind of professional help. Here's a start, call the Samaritans helpline (08457 90 90 90), they can support you and give you the right information about what steps you can take to get the right kind of help. Just, try to switch off from your thoughts every once in a while until then.
