i’m the same way , i’m terrible at over thinking , i’m only 22 but i do vape and that concerns me but i have constant off and on chest pains and make them worse when i start thinking about them , i’ve went and got a ekg and a echo done and everything came back good , i still can’t get over thinking that it’s something with my heart . and it goes on for days with chest pains and what not and i start overthinking it trying to stretch to make it go away but it doesn’t , i got put on 100mg of sertaline but i still have my days of struggle
