What should I do if anything?

I am 16 years old and am only writing this question out of curiosity. I am very lonely and I think maybe depressed. I stay home playing video games and read books b/c I have no friends near by cant drive and have moved so many times I have lost count My dad is constantly at work b/c of obvious reasons. My mom is home b/c she is disabled. I find myself desperately clinging to old friendships lost to constant moving. I really don't want to talk to my parents about this b/c I am shy, timid and I don't want anymore change. I am just looking for some responses that may cheer me up or give me an idea of what I can do. I even made a new account to make sure nobody I know can find out it is me. Most of my friends think I am very happy go lucky but I have thought about suicide many times but am to scarred of what comes after death to do it. So I don't know what exactly I am looking for but maybe if you have been in a similar situation you could help.
