Life restart

Hi all. I'm currently 27m trying to get my life together. I live with my mom and dad and brother. We went through a very turbulent time and lost everything. During that time I drank a lot and made many mistakes, lost my girl who then moved to Brussels. Since then I've put in a lot of work but don't have a stable job. She still wants to be together but is two years older and ready to settle down. I'm currently going to AA meetings and trying to recover from alcohol and weed. I really want to get to her but I'm trying to invest in my sobriety. Either way I feel completely confused and isolated. Do I wait for something to happen or go get serious work. Stay where I live or pack everything and figure It out in Brussels. I fear I don't want to bring my problems there. I did a politics and history degree but that's done nil to help. Currently I don't know whether to move on here because I know that if I get full time work and get a flat and all then my dream of Brussels can get further away. Please help thanks !
