For the past month or two i have constantly been under the anxiety of feeling like i’m going to have a heart attack. it mostly happens when i’m going to go to bed i end up thinking about it too much and start to panic. btw i am 17 years old so the chances of me having a heart attack are slim too none. despite knowing this i still stress out over it. I have had bad anxiety for my whole life but it’s never been as bad as this. what should i do? also i would rather try things that don’t involve medications. thank you to anyone who helps me bcus i really just need to get some good nights of sleep.
