I am a 39 yo male, who after years having fun in life I know come down to earth and realized that I have a destructive pattern:
Meaning, I destroy everything behind me, that includes great jobs, great opportunities, relationships, social interactions, relation with banks and whatever.

I am now in a moment in life where I have no money, no friends at all, I have a job, and for the last one and half years, I change countries 4 times (I live in Europe).

All this thing leads me to isolate in my room, I spend weekends without talking to know one, just Morning to cashiers and going to the gym. I am single and not even want to go out at night because I feel like at my age I should have a stable life by now and that makes me feel shame, so I avoid to meet people, especially of my age.

My mental battle now is to try to understand what makes me have this behavior.

Am I alone on this? Is there a know destructive psychological pattern?
