Where Did My Life Go?

I suffered a TBI in June of 2015. Since then I’ve lost my 15-year position working for the court system. I ended up on disability. Before my brain injury I worked two jobs, now i have none. The depression I feel inside has destroyed even my marriage. I feel so sad and alone. Looking for some type of support group that i can talk to because i dont even understand myself .Please comment if you have suggestions.
