Firstly I would say do not worry about what other people think of you, if Jesus had worried about that He would never have come and did what He did.
Secondly you can never 'prove' God, it is pointless to try, there are a few Christian sites that have very counteractive arguments, but I have found that most atheist scientisits refuse to accept anything they say.
Believeing in God is a heart work, hence why we cant prove Him in the sense science wants.
Just carry on being you, ask God fro strength.
