Honestly i had panic attacks many times in the last few years, see a psychiatrist, or therapist it helped me out BIG time!!
My issues were because i worry to much, about every little thing. Having someone tell me i was ok and all i needed was meditation, yoga or something that let my mind relax was what helped me. In the last 2 years i lost a job of 7 yrs, had a bad car accident that wrote off my car, and had 5 close friends die. Ya sometimes the brain gets overlaoded with bad feelings and it needs a vacation, hope u feel better
