Oh, I did too!!!
Frist of all, congratulations... and you are going to love it!!!!
Second, for me, I did have some pain. However, nothing unbearable or that didn't make it totally worth it.
I was out of work for 2 weeks. When it was time to go back, that was okay. Since you mention you are in school and will be having this done during your break, you may want to invest in a rolling backpack (I can't imagine trying to carry books or a bookbag or even a backpack on my back anytime soon after the surgery).
My parents came down for about 4-5 days after the surgery to help me out, which was great. Before they left, I made sure everything I would need to reach (glasses, bowls, etc.) were on the counter within easy grasp (raising my arms up/above my head was difficult for about a month). I was lucky enough to not need drains, and I also really didn't change bandaging... my surgeon had follow-up visits scheduled, and bandages were changed at those times.
Also, PRIOR to surgery, look for some good athletic bras... the kind that zipped up the front were easiest for me (due to not being able to put my arms up much at first). I would also plan to wear button-up or zipper tops for awhile (again, just easier until it was more comfortable lifting my arms). There was some scarring, but again, nothing that I can't live with or that would make me not do it again. There's a liquid scar treatment, called Scar Guard, that you should be able to get from your doctor's office. This is good, and you can use it after the stitches come out. Mederma is also very good (I wish I'd known about that one right after the surgery). I tried Scar Therapy too, but wasn't very impressed with that one.
After surgery, don't be too shocked if you feel like your breasts are sitting up high - like directly under your chin. lol After a few months, they start "settling" into a more natural position.
While my parents were helping me, I pretty much did nothing. (They were great that way!) BUT, if I had to do it over again, I would try to be a little more active. I don't think I started fully recovering from the surgery until I started moving around more and doing more for myself after they left.
If I think of anything else, I'll certainly post! I would most definitely do this again in a heartbeat and think you're going to be very pleased! Good Luck!
