True or Wrong Friends?

Hey there!

Did you ever think about the type of your friends? Are they good for you or the opposite? However, here is something I wanna share with you.. It is about "Friends".. When I was in primary school, I have some friends, I thought that they are the best, but then I realized that they are not my friends again when we stepped in secondary school. It's like, I'd never exist! When I meet them, on the outside they seems kind to me, but on the inside, the truth is they are so not wanna be friend with me EVER again! One of my friends had turned into a stylish girl and she thinks that she is cute and pretty.. Well, I admit that she is pretty, but not that pretty though.. But, I realized that when I was with them in primary school, I never FAIL in any subjects although it is in a chinese school! But, when I had found SOME new friends in secondary school, I don't pay much attention in the class and they always talking about are GUYZ! Hate that! I don't show that I hate their attitude, I just kept quiet so that no one will be hurt.. That's what I think. Until, one day, I had a crushed on a guy in my school and they want to tell the guy about my feeling.. But, I stopped them. On the last semester, I failed my Maths subject and that is the most humiliating thing I ever done! I was really regret! I am thinking, was this about my attitude or it is all because of my friends and my bad intentions for them? Oh, what I'm gonna do? I think I'm really in a dead end! And one more thing, yes, I admit it. I don't really good in Maths and Science, but I have such a HUGE interest in becoming a Doctor! I think it is good to help people and I can save many lives if I am a Doctor.. Hmmmnn.. What I'm gonna do now? The exam is near!
