heartdiseasesecretreport.comHeart Attack Symtoms

ok im 17 and have anxiety i have always been a worrier. The thing that keeps anxiety stuck on my all day is my over-breathing its a problem where you breathe manually instead of automatically because your obsessed by it. The only time i seem to breathe automatically is when im playing xbox or doing something fun so my minds of it. My anxiety real bad so i got bad cheast pains exactly in heart area so what do i think Heart Attack started researching it and it made it worse because i had all the symtoms anyways i got heart checked about 50 time never a problem he said i am very fit actually and i have just done about every heart test possible. My anxiety still makes me believe im having a heart attack though its a bytch. I havnt been able to sleep cause im freakin out and i cant breathe throughmy nose sicne its so stuffed full of sumthin i hav bad sinus.it all just adds up making it worse. Always sweating in handsfrom anxiety its just annoying. it has my heart racing all the time aswell. So i was scared to exercise cause of the racey heart but i just found out that if you have anxiety you MUST exercise as it releases that adrenaline build up and stress. I heard to try yoga aswell. Now i always here people saying you cant die of anxiety but i was reading this thing on internet(never do this people never look on interet about problems you not sure of because it makes anxiety worse just see a doctor). now back to the part were i was saying how ppl say you cant die of anxiety i was reading that you can as it stresses out your heart so much you get heart failure i think from all the adrenaline or sumthin i think it was called a broken heart usually provoked by emotional issues like deaths and such but seeing that it said adrenaline and anxiety gives adrenaline really had me freaked out i still am i havnt slept fo ages. Please help i have my first appointtment with phycatrist or phsycologist i dono what there called on the 27th i think so thats in 2 weeks. i need something to help me in the mean time does exercise really help. and will i die that thing really has me freaked out.
Thanks
