Should I go to the hospital

Your best bet is to contact a charity like CALM or mind and to speak to someone on the chat line. If things are getting bad phone your local crisis number or dial 999. When you go hospital they’ll ask you if you want to voluntarily section yourself but only if they believe your high risk enough. You need to book an appointment with your GP even if it’s next year because you can’t get access to mental health services without them referring you.

I don’t know where in the Uk you are but nhs should have a mental health team where you are with a crisis line, you can self refer or phone 111 and they should be able to refer you

If you're feeling suicidal and have a plan to act, a hospital is the best. Call NHS 111 (for when you need help but are not in immediate danger) Contact your GP and ask for an emergency appointment. Contact the Samaritans (details below) Use the 'Shout' crisis text line - text SHOUT to 85258. Finally, it helps to do ERP for SO-OCD.
