Icy hot feeling and can't breathe

And just when I was about to fall into a deep sleep last night my heart starts racing and I felt a body rush as well

Off and on but it doesn't seem to make a difference cause even on my good days (days where everything seems fine other then these symptoms) the nights always end up the same. The only thing stressing me out is the fact that whatever this is i have going on is really effecting my life. I lost my job, have to stay with my parents, and can't enjoy life with my children all due to these attacks. However I can say that when I went to the hospital last it showed I'm still having problems with my blood ( mcv, mch, and 2 others) showing I have a type of anemia (which my PcP has known about for yrs) and some symptoms could be by that alone so for 2 days I been taking multi vitamins but even those make me feel bad. I'm gonna try to hold myself together a few more days, hopefully it helps alittle
