I used to be like that but just got fed up so I signed up for activities that I always wanted to do like acting, playing the guitar, and taekwondo. Best decision I made in a long time. I'd recommend signing up for a martial arts class (karate, judo, taekwondo, etc.) since exercising was the number one thing that helped me ease out of depression. Seriously, it did me better than any SSRI I took. If you take a martial arts class you force yourself to be surrounded by people, be more flexible, learn discipline, be able to defend yourself, and eventually show off your skills to others. It's never to late too join, there's lots of people in their 30's and 40's who come to class. Of course there's other things like doing yoga and going to the gym, but there's something about martial arts that makes me so drawn to it.
