I have this fear of having a heart attack. I blame my family for it mostly because they will never stop mentioning it in front of me even though they know I have Anxiety.

I get some overlapping symptoms from time to time like chest tightness, phantom pain in the arm, neck, etc. it stops me from falling asleep a lot. I know it's not anything to do with my heart because I've been to the Emergency a shit ton of times and everything is fine but in the back of my head I still cannot ever fully relax.
