I'm shutting myself in like I did when I was younger and I'm shutting all my friends out. I was getting really good at repressing this side of me but it just returned in full force and I dont know what to do. Every time a friend calls me to go out I get this overwhelming urge to decline, even though I know I should be with them. They are slowly starting to quit on me and its almost identical to how I lost all my old friends a few years ago. I can't handle this shit guys, how do I get back to how I was?
