I'm so lonely it's depressing ?

So, lately I have been feeling really lonely I want to talk to people, but I know I'll stutter so I just keep my mouth shut. My only friend is my cousin, and I love her dearly, nut I can't always talk to her about things because she us very Christian and I don't like being told I'm going to Hell. How do I get over being embarrassed about my stutter so I can gain some confidence and actually make friends?
