Can I get my attitude back... should I even try (Details Inside)?

I let the bastards grind me down, and I lost my morale 14 years ago in university. From being interrogated by the police twice for 3 hours a pop, and being dumped by my best friend and my girlfriend and failing out of university. All in two years. I am cooperative with my psychiatrist and I’m missing some of the chip on my shoulder, but that oomph is only slowly returning. How do I get my stones back? How do I get the courage back to grow a pair and move on? Have you ever let the bastards try to grind you down… How did you fight back? What works and what doesn’t?
Or should I keep quiet and slowly save money until I can have a safe adventure watching TV and YouTube ?
