I am kinda in your situation. Im a 20 year old college student. I'll be frank, package handling sucks. It is a very very tough job, and I wanted to quit when I first started in June (right after my birthday). I was especially frustrated during peak season, getting nearly no sleep, and having to maintain decent grades at a Catholic University. It actually gets somewhat easier after your first few months, you get used to the work. But they will always continue to screw you; you see, I'm the guy who always helps people load up their stacked out cars, but I never get that help when I need it, resulting in mis-loads. If your hub allows it, bring an i-Pod in to your shift, it really helps you relax. Just stick with it, and get out of there as soon as you can.
