Hello everyone, 
I’m a 20 year old M that’s currently in college. I would say that I’ve always been confident and relaxed about doing things but the past year or two life has been had other plans for me. I’ve developed this pattern of knowing that if I have to go drive somewhere or do class, my stomach starts to cramp up and I start to feel nauseated. I never had this happen and then suddenly my whole life has just felt like I’m limited to go outside, it’s like my brain senses that I’m doing something new or stressful and my body just wants to do everything it can to prevent me from doing the task. It’s difficult to deal with because going to an online class, Ill wake up early just to throw up and use the restroom multiple times. I’ve tried deep breathing and CBD. Cbd has worked to a point but still the main issue still remains. The weirdest thing is that mentally, my thoughts are fine and I know that I’m fine but my body doesn’t listen. For some reason the moment the activity is done or that I’ve been driving for a long enough time, my body calms down and I have no symptoms. 
I’ve been to multiple doctors and they can’t find anything wrong. What would be helpful ways to help me learn to deal with this and hopefully make progress back to a normal life?
