Me and Mary Jane love hate relationship

So idk if yall go through this but I’ve probably been smoking MJ for like threeee years on and off with long breaks. Now I’m down to a few puffs of a joint a day and wanting to quit for good. I’m getting overly paranoid now specifically because if I get a bump or sore in my mouth or pain anywhere I instantly think it’s something horrible because of the smoking and I can’t knock that feeling anymore how do some just not even care because I love weed but it’s also ruining me as well cause I think I’m gonna die from smoking every time I get any kind of health “problem”. Thanks for reading my dumb a** vent at 12 am.
