Waking up abruptly+ feeling faint

[Bojax]

Hi I'm sort of curious if anyone else has experienced anything similar to my problems. I don't know if my problem is just a general anxiety thing or if it could possibly be tied to something else?

Maybe once a week after struggling to fall sleep I'll jump up randomly into a startled semi-awake state less than an hour after I fall asleep. Since I'm sort of dazed and confused as to what woke me up I usually get up suddenly to go check if there's anything visibly wrong with me in a mirror and sometimes I feel faint like I might pass out, although I've never actually fainted.

I'm mostly worried about feeling like I'm going to faint is that just a head rush from switching from a sleeping position to instantly getting up and walking around?

Thats happened to me before....it was an anxiety thing per my doc. Does not happen very often only happened a few times.

This happened to me also.  I actually almost fainted...everything got black but I never actually fainted.  It was very scary.  Now when I get up, I sit on the bed for a moment and get up slowly.
