I was sitting there just casually gaming as I do before bed. I stood up cause I was tired and my body just went into anxiety attack for no reason that I can think of. My heart felt like kt was racing, my body's shaking, I felt like I was dying numerous times after about 15minutes of me not being able to calm down I really started worrying so I went to the hospital. This anxiety episode lasted around 40minutes I just felt like I was dying, my body wouldnt stop shaking, i had very short breathe, and i just felt out of it like light headed but of course it was just my anxiety but I've never had an attack so bad before I had no idea what to do and it scared me so bad I truthfully thought I was gonna be gone last night. I hope I never experience that again.
