What to do?

Any of you ever feel like you just don’t have a purpose? Day in day out is the same thing over and over. Sometimes I just don’t even feel anything. I don’t feel my life progressing, I don’t feel like I should be here. Theres no reason for me to be. Feel like I have no friends whatsoever. Crazy how you can be surrounded by people yet feel so alone. I don’t think many others really understand that. Your mind can be your own worst enemy. Been feeling like this for the past 4-5 years now and haven’t done anything about it because I’m so petrified. Just feel at a dead end.
