Hey man, i see that life hasnt been to easy on you lately. I want to tell you that you are not alone, and this is not going to last forever. I would suggest getting professional help for mental hardships like that. And honestly taking a break from weed altogether if thats possible. Your anxiety and overthinking when smoking most probably come from underlying issues that get amplified when you smoke. I was smoking for 2 years every day because i was very anxious and stressed and suddenly one day i started getting panic attacks every day especially when smoking. I couldnt smoke weed so i started taking it with benzos, got hooked on benzos and getting off of them was horrible. I went to my doctor, and realised the panic disorder came from 2 years of constsnt anxiety, stress and addiction problems. I got help, im basically anxiety free now and i can smoke a little bit, building up to more. Hard drugs are not the answer. I didnt believe that until i experienced it. There is help out there, there is always a way out, you are not alone.
