I don't know what to do?

I was exactly like you and I know how it feels to be quiet and shy. I picked up a hobby and made friends there. I also have gotten really close with the poeple I work with. All you have to do is start asking people vague questions and as the days go by start asking them more personal questions. As you become closer with people you will find that you will want to hang out with them outside of your conversations. I realize it is easier said than done but if you just start talking to your type of people, talking and hanging out with them and other people will beome much much easier. I wish you the best of luck and I will pray for you,
