Seriously, do you like hurting yourself! Starting a post saying, "no body likes me", is either blatent attention seeking or you genuinely think that you are the least attractive and appealing girl you know - both are stupid, and a clear waste of time.
Now i know someone is going to say that i'm a **** or insensitive or something, but I dont care.
You have to grow up, this whole playground thing is stupid. The whole, I'm not sure if he likes me, or his friends point... is complete rubbish. Yes, you maybe shy and worried about what he is going to say. Well guest what, EVERYONE IS! No one is totally confident in themselves! Get over yourself and I promise you will start feeling the rewards.
This is what you're going to do, no excuses! If you like him, and want him... You go up to him and say Hi, how are you...blah, blah, blah. I like you! Thats it: I like you! And I would like to get to know you better. Lets go out sometime!
What have you got to lose? Seriously? People may laugh! Big deal! People that laugh at other people are insecure! Even if you don't feel confident, Act it! The old saying that anything you want you can work to achieve it, is true.
Sorry for being nasty. Digging yourself a hole like this is not only stupid, depressing, pointless and self-defeating - it wont help you get what you want. You sound like a sweet girl, and making this post shows that you have a good heart. Take the risk... you may end up with what you want..
Good Luck
