idk if it’s my anxiety or im exhausted

my heart is getting nervous for no reason like a sudden nervous feeling and it feels weird it doesn’t hurt or anything . also when i get it i don’t wana eat i gag and throw up alittle and get nauseous .

idk why i’m getting that.. i workout too so idk what’s the problem... it’s like a weird feeling wheree you find something out like ur man cheating and feel sick to ur stomache but it’s ur heart .. is it anxiety or something else? should i get checked.. it doesn’t feel like anxiety just nerves. should i get anxiety pillls or what? i feel like whenever i get that feeling , and i throw up , i feeel better when i throw up becuse i’m releasing the bad stuff.. and please don’t tell me soemthing scary to hear cuz idk if i can sleep
