What should i do?

Sounds like you've got a bunch of issues. No matter.

I was in the same situation, with the guy I like having a girlfriend. At first, I was rather unsure about how I should feel, but then I remembered that as humans, all we want is happiness. Since the guy I liked was happy with another woman, why shouldn't I be happy for him, I asked myself. So I accepted that he had a girlfriend and secretly wished for the best for both of them.

As for your friend liking the guy you like, there is nothing really you can do about that. It's not anyone's fault that your friend starting liking the guy you like. At some point, we're all going to experience something like this. But like you said, the guy you like has a girlfriend, and judging from the advice I said above, I think this problem will disappear soon enough.

You need to tell your friend that you feel left out about what she's doing. Figure out a way to compromise and equally share your friend with the other person. Who knows, you could gain another friend out of it.

Worst enemy? How so? Anyway, although this might be far difficult, try to befriend your enemy. Try figuring out if you have any similar interests, and if so, talk about them with her. I recall reading somewhere that whether it be a friend, an enemy, or a neutral person, that each person wants nothing but happiness, and does not want to feel pain or hatred. You should see this enemy as a friend rather than an enemy.

Your mother is simply concerned about what's going on with your life. Perhaps you should try and figure out why it is your grades are so low, and then try to fix that problem.

I'm sorry if I didn't address all your problems to the best of my ability. You did ask a lot of questions after all.

just carry on the way you are if it really bothers you ask your mom or one of your friends for help

or ask the people that are make your life suck why they do that

or mabey you need to pick better friends
not to be mean but yeah.

if this doesnt work sorry just trying to help

Sounds like you are having a series of unfortunate events. Take a deep breath and relax.
So, the guy you like has a girlfriend. If I were you, I would move on and find someone new. He is content with someone else and you need to respect that. If ever he does break up with the girl, then at that point, you may pursue him. In all honesty, he sounds like a lost cause.
As for your friend.....she isn't your real friend. She ignores you and is hanging around with your enemy. Not cool. Definitely make new friends and avoid her at all costs. She isn't a real friend. A real friend would be supportive of you and would not ignore you. On a side note, your friend that likes the same guy you like.......she's in the same situation as you. He is a lost cause and you both need to respect that he is with someone. He is off limits and you both should move on. Also, I think it is best if you don't share who you like with anyone, except for your maybe your mother. (That's what I do) Because you told your friend, she now likes him. It's that whole thing where some people want everything.....
About the grades.......listen to your Mom. She is only looking out for you and wants you to excel in life. Grades are very important. Focus on your studies!!! They will benefit you later on in life, trust me. Just talk to your Mom and ask her to ease up on you and not be on your back 24/7. Talking things out always helps.

Don't worry.....your life doesn't suck! You've just hit a little bump in the road. It happens to all of us. Just fix up that tire and keep headin' down that right road. (Sorry for the cornball metaphor!) Best of luck to you! :)
