6 months? As if that's a big deal...
You may be feeling lonely, but that shouldn't make you feel the need to get a boyfriend. Don't think that a boyfriend will miraculously change your life and everything will be sweet. Firstly try and find some friends or if you have friends, just try and put a bit more effort into socialising and going out with them. I'm shy too, but we shouldn't use it as an excuse. good luck.
