Stressed with school...?

I just can't stand it anymore. I used to be decent with everything, but now that the work load is getting worse, everything seems to be falling apart. I'm a junior in high school and, honestly, I have no time for anything. I try to organize my schedule, it doesn't work. I get to school usually an hour early every day for rehearsals and whatever else. I usually have 2-3 hours of homework every day, not including any projects that I have due. As much as I study for my history cl, I can't retain any of the information, and I'm just not doing well in that cl. I don't usually get home until, at the earliest, 6:00 in the afternoon, and, not too rarely, 8:00 at night. At that time, I have to handle all of my homework, which takes me until about 10:00 or 11:00 every night. After that, I use my 'free time' to try to memorize the music that I have to know usually within a week or so. Right now, I have to learn 5 pieces, one for snare, one for toms+cowbell+b+cymbal, and 3 for another instrument. At the same time, I have to completely memorize a piece that is the hardest music I've ever played in my life. On top of that, I have to learn all new drum rudiments and all new things on my other instrument, which isn't any easier. And ON TOP OF THAT, I have to worry about trying to stay in shape because of something I need to do over the summer, which I'm not exactly ready for. Then I, at 17, have to try to fit in all the time that I can (usually not much) for chilling with friends. I have no time to have a girlfriend (doesn't work, I've tried. They just get angry that you 'don't want to spend time with them'...well...I don't have the time to spend...anyway...). I have no time for a job. I can't even find the time to learn to drive (which I can, but I need to improve a bit...). And even then, I have to take care of stuff around the house and do all of those kinds of things. Honestly, I don't know what to do about it. I mean, some of the stuff is fun if it's in my free time. But when I don't have time for something, how can it be fun to work it into my schedule? I like drumline, but when it gets in the way of everything else, how could I be expected to do well at it, and why should I be required to attend? Does anybody have any tips on how to work all of this into some kind of schedule...I mean, I just can't do it. Right now, I'm seriously not doing some of my homework (11:01 pm and still at it) so that I can write this message. I'm just pissed that I can't seem to find any free time. I can't get a life. I don't get to really be a teenager. I don't have the time. Anyone have any advice? And for those of you who'll tell me to, I'm not dropping band...
