Geez, that doesn't seem very fair of your mom to say that. :| At least your dad is more worried.
Well- have you tried talking to a school counselor, the principal maybe?
If there's a teacher you feel particularly close to, they're worth a shot. Maybe they'll be of more help than you imagine. =]
I don't think it's such a good idea for you to be skipping school though.
You're missing important work ! It's true that you could just borrow someone else's notes or something, but they'll never bother teaching you as well a second time ( if not, at all ).
I bet I would have preformed much better on my finals if only I didn't miss so much work. :l
I also don't think that it being "suckish" and having too much drama are valid reasons for skipping out.
Unless the drama actually involves you, what reason do you have for not going? School can actually be kinda fun once you know the right people for associating yourself with.
Just hang in there ! The bullies that made fun of you won't always be around- if not, it's about time they grew up and start focusing more on their own problems. ;]
Though if you're being miserable and acting mopey, it can have a DRASTIC effect on the people around you.
It's something that I keep failing NOT to do, and I end up being a huge jerk. \:
Say you act like a cow to your friends. They're probably not gonna be acting much nicer to you themselves.
If you cry in school / class, then you're more emotionally vulnerable, and you're an easy target for more bullying to come.
Act like all this drama doesn't bother you, and tell them to cheese off ( of course, a bit more politely, if you will xP ).
Overall, I really hope things will be better for you soon. Good luck. =]
