Yes.
ask yourself
No.
Just be yourself and act as if everything is normal.
You cannot force someone to feel what they may not. The best tip is to be yourself and ask them out - get to know them better and let them get to know you.
You can't force anyone to like you. Be yourself around your crush and if they end up liking you then that's great(: but if they don't then don't change yourself for them. Find someone who will love you for who you are.
Put yourself out there. I know it can be super scary, but sometimes you just have to make the first move. ----- Find out what your crush is passionate about. ----- Buy your crush a gift. ----- Be yourself! ----- Talk to your friends about them.
The only way you will find out if you really do have a crush on someone is to speak to them. You need to know one way or the other if they feel the same way, at least if there is any chance if your feelings are worth carrying on with. The longer you have this feeling without doing something about it, the longer you allow yourself to be hurt or confused and frustrated.
Try to befriend them and gain his/her/its trust. Carry yourself in such a way that she/he/it will admire you.
Hmm,... Well number one, take some time for yourself.
Ask yourself is this someone you want to be around everyday and be in a romantic relationship with. If yes, then you probably have a crush on him and should probably let him know how you feel in order to see if he feels the same way about you. If not, you will be torturing yourself.
course it is, at my school its certainly possible :P other times you just reach a point where you get over yourself and figure that a crush is a crush and you wont marry the guy or girl.
Stop putting yourself down, and start building yourself up! Get a good book on "How to improve your self esteem" and study it, work at it. There are no shortcuts. Do the work and it will pay off big time.
