First of all, I know exactly where you're coming from. I've been in your situation, and still battle with it today. I can understand how panicky you are right now and stressed down to the last thread. Do you only have this weekend to complete all of that? I suggest you make a schedule for yourself to do as much of each project as you can complete. What's better than a 0 is whatever you can finish. Never stay over two hours on something, unless you know how to finish it. After you're done with other things, you can always go back to it. The violin thing, I can understand how frustrating it is when you can't nail something on an instrument. Druming could be very difficult for me at times, but honestly, practice makes it better. As much practice you can get with it, the better you'll get at it. You may not get it right, but it'll surely get better...I promise you that.

One thing you'll need to work on is time management. Keep an agenda/planner, and try to work on things ahead of time. If you need help with something right away, you need to let someone know. Like your violin instructor, for instance. Do not be a procrastinator! Plus, once you get it done earlier, it won't hang over your shoulders the rest of the time you wait to finish it. Tutoring is not a bad thing either...at least the teacher will be able to get you started on an idea or direct you without you having to stress over it.

I wish you good luck, and if you need ANY help with ANYTHING at all, we're all here to help you, as well as me. I'm willing to help you with anything to make it move along faster for you (especially the english stuff...I love writing). =)
One more tear falling down your face
doesn't mean that much to the world
One more loss in a losing life
doesn't hurt so bad anymore
