same thing happened to me. i spend 20 years drinking, smoking weed and playing wow.
i finally got my shit together. become sober and finally got a job. worked for 1 year and noticed this is just unbearable way of living. maybe i got 200e more on working than just on welfare.
thank god i live in nordic country where it easy to go back neeting. now i just somehow need to find purpose what to do next 30-40 years
