Well its a chain reaction, and when you reject the most obvious of links, its only natural that you get nowhere in your endeavor...

T says get a job or volunteer, or get involved in a hobby... This will lead to less time in your bed, a routine of some sort, and the opportunity to meet new people and make friends.

You take the first step, realize friend making is not going so well, then you quit and end up in bed for months on end again.

A T can't make you try, a T can help facilitate your goals, its still up to you to reach them, and no matter how many Ts you see or how lonely you feel, its important to remember that nothing comes from nothing.

Have you tried interacting with your housemates again, or have you given up on befriending them?
