I rarely get serious panic attacks, and nowadays when I do its related to losing money or something of he sort. In the moment when it happens my panic/anxiety attacks are quite strong...heart starts to beat really fast, sweaty palms etc. the lot...and then it gets to the point where I start to feel unwell (like ive reached a limit) Kind of a feeling like I want to puke or pass out.

I'm getting worried that I could give myself a stroke/ heart attack with one of these.. Even now I'm very controlled even going through these..but it feels absoutely horrible (like death basically) And even knowing what im going through my brain is trying to get me to scream out for help or something similar (reptilian brain) But as I said my biggest fear is getting a heart attack with one of these?
