Oh, I get it now. I guess I could do it, even though I'm a bit germaphobe, I don't know how weel I could do in hospitals..

However, I think the problem is actually another one: it's not only that I don't know what to do (even though that plays a big part, too), it's that I don't find the MOTIVATION to do it. For example, I recently bought a guitar to learn how to play it, but I got discouraged pretty quickly (a couple of weeks) and I stopped playing it.

That's what I was referring to: I don't have any hobbies or interests, and I have trouble finding them because I get bored with them pretty fast; and this makes me sad and hopeless
