I’ve been having really bad anxiety ever since last summer and lately it’s started to get worse like I just have this feeling I’m going to get a heart attack and i don’t know why every time i think about it i start having trouble breathing , my heart starts to feel weird , and my shoulder starts to hurt it’s not like i want to think about it . the thought of it happening just stays in my head and i can’t find anything to do to make it go away it’s gotten to the point where im loosing sleep over this because i feel like something might happen while I’m laying down i really want to know if this is my anxiety or if it’s something wrong with my actual heart and if it is my anxiety what can i do to take my mind off of these type of things
