For the last 6 months I (16F) have had some pretty weird symptoms. 
Every night before going to bed I’ve had a weird taste in my mouth, that never goes away, and that makes me think I’m gonna throw up. I have a really bad phobia of that. Every night I also feel very nauseous, but that’s mainly when I have school the next day. I always feel like I’m gonna be sick, my stomach hurts. Even when I shouldn’t be anxious about anything, I feel anxious all the time. I’ve had chest pain pretty often too, I couldn’t breathe. 

Does anyone experience this too? Are these because of anxiety? Is it normal? What can I do to get rid of this?
