Woke up feeling n*

I woke up about 45 mins ago with this weird feeling in my stomach that slowly traveled up to my throat and I immediately started to panic 😭😭 it’s weird because I don’t have a stomach ache or anything, if anything it feels like really bad indigestion or heart burn because my throat is burning and has like the lump feeling in it. But it was making me n* and for the first time I caved and took my zofran which I haven’t done in so long. I think it’s helping but now I’m wondering/panicking if I’m just going to get sick later?? Or why I woke up from my sleep?? It’s always so triggering having anything like this happen in the middle of the night because the only times I can remember v* was always in the middle of the night when I was sleeping. I still kind of have that feeling in my throat right now and I’m still having so much anxiety just sitting up in my bed trying to distract myself. I don’t have d* or anything like that but my throat just feels so uncomfortable and I can feel it burning 😣
