Trying to Keep Busy, but I'm too Busy Doing Nothing

I've been having a bit of a problem with the way I have been spending my time lately. I get home from school and sit on my bed. What do I do? Surf the web! (Look, I just wrote a cute, rhymey song.)

But in all honestly, I have been spending far too much time on a certain infamously time-consuming website where I am bombarded with beautiful pictures and GIFs of my favorite actors/characters. Yes, Tumblr. There are other ways to let time waste away, though. I am just very bothered by the fact that time keeps slipping away from me.

The only solution I can see here is to make myself busy again. Aside from the mythology quiz I may have failed this afternoon, school is not challenging at all. I have hardly learned anything new, and frankly, it has become a wearying pattern of boredom. My mind can't handle it any longer. I'm actually getting quite depressed, which isn't as fun as it sounds. So, some ways to keep busy:

1. Get another job. This would probably be the best choice for me since my current employment situation in a bit more rickety than the woman originally led me to believe. I'm looking for something that won't restrict me as a person because I am incredibly finicky when it comes to my time. (And why not be that way? I only have so many days left before I die.) I will be applying to small shops, but I'd prefer to find something I can control, such as cleaning, more babysitting, or even homework help for kids. I'd go for anything, honestly. Getting started in those will be a challenge, but a challege will be sure to keep me off the internet.
2. Join some sort of club. I have to do this anyway, if I want to keep my scholarship, but I kind of missed the expo because I was too shy to approach the tables. Oops. Time to try again.
3. Start a new hobby/sport/work out. I've always written, played music, and painted, but I think my mind needs a change. Perhaps a shift towards something more active would benefit me. I miss having access to a climbing gym daily, which was my favorite part about high school. Now, there's nothing to look forward to in my day, no mystery. If I started channeling my energy into something like yoga, swimming, climbing, or even running, I would feel a lot better. Still, working up the courage to go do those things is hard. I am the one standing in my way, here.
4. Volunteer work. Last fall, I volunteered at Crabtree Nature Center, and it was very relaxing. I got to spend time out in the forest and learn new things about nature. Everything about the place was serene, and I wouldn't mind going back to that at all.
5. Hang out with friends. This one is always fun, and I do this. Only my circle of friends has been largely diminished, so the time is limited. Branching out is hard for me, especially since I don't form bonds with people very easily. Still, I love spending time with the people I love, so if I do more of that there'd be less of a problem.
6. Start doing weird things again. Last week, my friend and I dressed up as characters from a TV show and went out in public. It was a lot of  fun, and it got me thinking about how I used to do sily things like that all the time. If I stay silly, I will stay happy!

Being bored all the time has me feeling a bit depressed. I'm not learning anything at school, there's no sense of mystery to my day, and I have no way to spend my energy. I'm really going to try to do a few of these things and more, and hopefully I'll pick up my optimism again!
