Health advice...

For some background I’m 19 and get anxious quite a lot.

Since yesterday night I’ve felt weak and what I can only describe as just weird. I’ve felt odd hot tingles go across my body and I’m not sure if that’s just an anxious feeling or something else...

I’m also convinced my breathing isn’t right, im not struggling or in any pain but idk im just convinced. I also keep putting my hand on my chest and I’m convinced my heart rate is going too fast.... well idk, could my head really make me feel like that without there being anything actually wrong??
