This boy that I like goes to my church and every time I get around him I feel werid what should I do to prevent that , he likes me but I don't know what to do ?HELP??

I don't think weird is a feeling. You should start by identifying the feeling and trying to understand what it is your feeling and why. Simply understanding it can help wonders.

Its okay that you feel weird. It is a part of growing up. In order to help you feel normal around him, I would say put things in perspective. If you like this boy, and you think he likes you, then tell him. If the idea of this weirds you out, just relax and be yourself when around him. That way he will see the genuine you and you can stop worrying about what he thinks.
