Flare-ups in class

This is the typical scenario of me sitting in class while a flare-up starts or continues form when I first wake up:

Should I leave? That is what I ask myself while I am sitting in class having palpitations and trouble breathing. With a touch of lightheadedness, do I risk trying to leave to catch my breath? About 50% of the time I will because I haven't actually passed out in over a year. It is just the constant feeling of passing out that I feel. Yes, the chances of me actually passing out are greater than probably every person in this room but I do it, I leave. Where do I go? I go to the bathroom stall and pray that nobody else is in there, so I can take deep breathes. So I can crouch and take deep breaths and cry a little as I try to make my body cooperate again. This usually fully works about half the time the other half of the time it makes it a little better but is still there. They don't even know, my professor doesn't even know that I could pass out as soon as I stand up. Then when I think about that, the professors response of me passing out plays through my head. All hundred possibilities of their reaction to me passing out goes through my head. At this point I am not even paying any attention in the class. I am just there for attendance and some notes that I won't remember taking. How would my classmates respond? Why does this even matter? I would never get to see their initial reaction because I would be sprawled out on the floor, unconscious. Either way, if I am free after class and have a little time to rest up then I do. I go back to my room and try to rest even if it is just for a half an hour because that can make all the difference. I am always exhausted after a flare-up.

There is also no point in trying to explain to anyone what is going on. If I do end up passing out or falling down or something; I would just show them my medical alert bracelet and tell them that I will be fine. That is what I am going to tell my future professors, I am going to have to tell them that I am at risk to pass out. And what to do if something would ever happen. I do not like having these conversations but it has worked in the past. I sort of warned a couple people, one of them including a professor, that I went on a trip with and I ended up going to the ER. I never passed out, I almost did (of course) but I had to go to the ER or I would continue to get worse. So, "warning" professors and important people in m life about what can happen, is what I am going to have to start doing from now on.
