I’m a 18 year old male. I was getting heart palpatations couple of times and mostly chest pains for a while so I went to get it checked out They did tests and everything but I never got called back for another check up so I’m guessing I’m okay or they forgot since covid or i don’t know. 

I been having bad mental health and anxiety to the point I think my overthinking is really bothering that I can’t even manage to go to sleep thinking I might trigger something 

I’m extremely worried I keep thinking I can cause a tumor by having these kind of thoughts

I feel like this all these suggestions of a tumor or heart pains thinking I might be in risk of a heart attack or cardiac arrest 
. I have been using Google so that’s why I’m so worried
