I will walk around e streets or home from school or any were and I will go through this episode that makes me feel like I'm sleeping when I am awake. I get really warm and I feel like I'm about to collapse and sometimes I actually do. I start to breathe really heavily as well I don't know what is happening and its hard to think when this happens. I have seen doctors and all they say is I'm claustrophobic but I don't think I am. No one can tell me what is happening and I getting worried. Can someone please try and tell me what is going on
