I don’t know what to do anymore

I’m so sad. Truly, truly sad. I have a few moments during the day that are nice but then it’s gone. I have nowhere to go, and no one to talk to. I go to therapy every week, but it’s not helping at all. I feel like I’m worse now than when I started a year ago.
I just don’t know what to do. I don’t know how to get better. I take medicine every day and try to do the right thing, and I’m still miserable and feel like disappearing.
