Too tired to do anything fun, too bored to sleep...

So here’s my situation… My job right now is currently an on-call sub position, meaning I have huge chunks of time off. When I’m off, a lot of times my parents will have me come out to their place (small farm, about 70 acre) and I’ll be working there. At the end of the day, I’m really bored, kind of sore, and kind of tired.

My problem is, I go home and feel like I should go to sleep, but I’m just too bored. Or I feel like I should do something fun, but I really don’t feel up to it. I’m single and not seeing anyone right now, and honestly don’t feel like looking. I don’t have cable or internet at home (I’m posting this at a wifi hotspot, in case you’re wondering.) I can’t handle alcohol well, so bars are out. I’ve seen all the movies I feel like renting multiple times, and in any case I’m so braindead when I get home that even if I rented one, I wouldn’t enjoy it. I’m usually exhausted when I get home, so forget exercise, even a short stroll. When I get home and it’s a dead night on the tube, such as tonight, it’s even worse.

Does anyone have any suggestions for how I can get over this feeling? Useful suggestions only please.

You need a pet, maybe a bird or a fish tank. Or a plant, anything living to take care of.

Can you get cable or internet at home? You need the Inernet, for real.
