How do you ask for help when its so hard?

Please seek help asap. If you go to college/school there will probably be a nurse on site or a counsellor, make an appointment to see them. You could even go to your GP. I can't imagine how hard this must be for you, but you need to realise that once you have got help things will start getting better. You can get through this. Stay strong and be brave, it'll be ok.
