does anyone else also get panic attacks while exercising? or even when you just go for a simple walk? my heart always starts to palpilate, i get dizzy, i get shortness of breath and i get waves of discomfort in chest which is very awful and i always think that it´s something wrong with my heart. i have got a EKG and everything was fine but i just can´t stop thinking that there´s something wrong with me. i always loved to go on walks or go for a run before my anxiety and panic disorder ruined it. :/
