I gotta ask, is it the mono talking? Mono sucks ass. I've never had it but I've seen it rob friends of their energy, drive, creativity, and even ability to hold a conversation. If I knew you and your situation better, I might tell you to just accept that you're going to be down for the count for up to a month or two. You need to take care of yourself a lot--vitamins and rest and trying not to stress about the big questions until you're well again. Since I don't know you that well, I'll just say that you should at least consider that it's maybe, partially the mono.
In the meantime, look at the pretty naked ladies and occasional pretty naked guy on here and let yourself relax.
