How can I stop feeling shy and awkward around girls.

i am a 13 year old male and I usually act as myself around girls and they say that I am really nice and funny etc but as soon as I relise I like them or they say they like me I get really shy around them and feel really awkward then I kind of avoid them and find it hard to be myself. it is really annoying because I can usually ask girls out and they will say yes but as soon as they do, I get really shy! please give me some tips to build my confidence please or else I will be alone forever :(.

What you're dealing with is something that most everybody goes through at your age. When you encounter something you haven't experienced before, it's normal to feel apprehensive and lose your confidence.

The good news is, you don't have to do anything but keep being your nice and funny self. It just takes some time and experience for the awkward feelings to go away but, trust me, they will. The most important thing to understand at this point is not to rush into anything you're not ready for. The people your age that start first often finish last by trying to make the journey to adulthood a 100 yard dash.

You sound like a really bright guy. I would estimate your chance of "being alone forever" at zero. :-)
