Are there any after-school clubs that you're interested in?
Try giving yourself a reward for working on the bass guitar. Like put off video games every day until you've practiced for at least an hour, or something. And stick to it. If you learn a skill it should help give you some more confidence.
As for jobs, its hard for everyone, especially students, to get hired lately. So I wouldn't take it too personally if you don't find one any time soon. Especially it being January right now; my store just let go of quite a few people.
As for acne I always used Clean and Clear before I started going to an actual make-up store. I have a green tea face wash that I like from Aveeno, too. If you want to start using products, remember to use a face wash that doesn't contain any medication in it first. Then you can use an astringent and a moisturizer with salyclic acid in it. Don't skip the moisturizer, and I wouldn't go for a spot treatment; it will clear up break outs but it will also make your skin incredibly dry and you'll have to remember to put on sunscreen before going out or you'll burn after only a few minutes in the sun. I find that a moisturizer with salyclic acid in it too works much better for my skin.
Hope some of that helps.
