Feeling Down

Ever since I graduated high school I lost my social life and don't have any friends. I have no one to hang out with. I stopped posting on Instagram, dont really have people to talk to. this has been going on for a year now and I've become socially awkward. I just don't know what to say to people without being weird, I don't know what to post or say. I'm not as pretty or in shape as I use to be. I just feel sad and lonely. I use to have such a fun a happy life. Now I'm stressed out about college and money and exams and my weight.
