Worst Life ever! HELP PLEASE!

I think i possibly may have the worst/ saddest life ever.

I am only in my teenage year but i have already started to drop my hair and have acne.My mom has pased me all these and although at times i blame her, i know its not her fault either.
I recently have a bad case of acne. i had 9 new pimples all in the timespan of 3 days. i dont know whether its because of stress, because my end of year exams are only 2 weeks from now.
Whats making me feel worse is that my bestfriend 's parents are on the verge of a divorce. So these few days she keeps asking me 'i feel so depressed at time, how did you manage to cope when your parents divorced?'
My parents divorced when i was only 9 years old and since i havent really talked to my dad. My bestfriend has also been critisizing my complexion , pointing to my pimples and looking at my pimples and saying 'WOW! wash your face! You have so many pores on your nose and your pimples are all over!' and she gives that disgusted face. i feel so heartbroken when she does that. recently, my face has also been very dry because of my desperate attempt to clear my pimples. My mom has also been quite fed up with me , saying i am so vain and conscience of my appearance. I feel very stressed when i see my face in the mirror cause i just feel like im very hard to look at.
As a girl, i have very thick eyebrows, buck teeth and pimples. I have heavy eyebags and my hair is dropping like crazy. On top of those, i am not smart at all , i fail math and chinese in school and don;t get As!. WHAT COULD BE WORSE?! i've been always to shy to talk to people personally and sometimes i doubt myself that im a splitzo. Someone who lives two personality. In school i'm so happy and cheerful but deep down inside i feel the pain but i dont know how to express it.

SOMEONE PLEASE HELP ME !! PLLEAASSEEE! I really need advice! I want to lead a better life and start to respect my self and body

You said it right there girl! You know what you want and no one is stoping you from leading a better life. Just by saying you want respect yourself and your body says a lot about how much of an awesome chick you are!

Hold your head high. Have a "who cares" attitude. Tell yourself that your an awesome chick and if anyone tells you otherwise......... "who cares".
Take care of yourself and everything else will fall into place

I wish you all the best and to help you don't try to solve the acne problem by yourself, try to go to a dermathologist (with recognize experience with acne) and follow all his or her instructions, next time your mom goes to the beauty salon ask her to take you to do something about your eyebrows... just tell to the one doing them to keep it natural, not like some models in magazines to keep you as natural as possible. About your friend, it looks like she is going through a hard time, but that doesn't allow her to make you feel bad, I think that she knows what she is doing, if she is your bestfriend I think that she knows you enough to know what can hurt you... so, she doesn't look at all like a friend...

I really wish you all the best, repeat that phrase every morning... "I want to lead a better life and start to respect my self and body"... don't forget it and keep it going on in your mind always, you will see how it starts to be a reality

Aww don't worry I guess.. Just try to enjoy life as much as you can!! You know, Tell your friend that its not your fault that your having pimples on your face and you're okay with it because believe me, I HAVE MORE PIMPLES THEN YOU DO and I am 13. I sometimes feel like crying but I do wash my face with a Face-Wash for Oily Skin every time I can. Just don't worry
