Hi grape, I don't think I've experienced what you are talking about here, but it might be some sort of dissociation or something (not a doctor, just a person who has her own problems with dissociation). You say you can't go to the doctor or therapy because your parents wouldn't believe you. I get that. But could you just ask to go to the doctor for something else (achy back, stuffy nose) and then when you are in there by yourself seeing the doctor you can explain what is going on? I do think it would be helpful for you to see someone. The instance you mention in the trigger is kind of disconcerting. If you think you are going to harm yourself or someone else please call 911. No matter what your parents think, your safety and the safety of others around you is paramount. I hope you can get a bit of relief, this must be very difficult to deal with. Do you notice this happens at a certain time, like when you are stressed or anxious? Have you been taking any medications that could cause you some discomfort like this? I hope you feel better soon. Be safe. HUGS Kit
