Depressed and no friends

I have been struggling with worsening depression for a bit now. One contributing factor is the fact I have slowly over the years lost all my friends… so I don’t have much of a support system or people to talk to/enjoy time with. Not that it’s necessarily bad— but my mom has now become my best friend and the primary person I talk to and hang out with. I feel like a drone on auto pilot… work then home every day. The loneliness continues to grow and my trust in people continues to decline. I even now resorted to downloading Reddit to try and find community and feel less lonely.
