What can I do to stop worring at nights about my inactivity?

I suffer from anxiety from the pressure that has extended from my school years… I’m always worried about being inactive and I end up signing out 20 or so library books on various subjects and only reading one or two. I’m anxious at nights and I used to talk to family and friends till 5 in the morning about my life and academics and gossip. I don’t have a job and I just sleep all day and watch digital TV. when something is good on…I recently signed out Don Quixote and I am finding similarities in situation…like for example I like to dream that I’m qualified to talk about religion, science and academics to the few friends I have…But now I’m bored I can’t seem to read any of the 20 books I signed out and most of the TV. programs are boring…I would like to go back to university but I don’t know what field to enter…I got so unmotivated and uncomfortable at my old job that I applied for disability and I got labeled as permanently severely handicapped and I get sent a check and pills every month… I did manage to save $2000 and I ended up spending most of my money on food and Christmas gifts… I really messed up and I don’t know how to fix it… I really don’t like my options….I don’t smoke, drink, use drugs or own a car, or own a house…I rent with my mom so I don’t have to deal with the boredom and stress from administrating my life. Counseling doesn’t seem to help and the doctors keep telling me to just go for walks…I don’t want to walk anymore, I am sick of reading and watching TV., all I do I sleep and avoid people…my doctor tells me that what I am going through Is a good sign that I am recovering…what would you suggest Is wrong with me? What should I do? What would you do?
