I can’t diagnose you as I am not a doctor.
DO NOT try to google your disorder because it will probably make you feel even worse and you should most probably go to the doctor or a nurse to get it diagnosed.
I understand that you might be too scared to ask for a doctor or something but Please, get one somehow. Even if it is an online free one- at least you’ll know what to do about it.
I’m sorry I couldn’t help.
