Depression & OCD

I have mild depression and the question of finding the meaning of life constantly looms inside my head. I also have some peculiar problems that only occur at night. I feel I have a second “conscious” in my head that would tell me what to do, which could be a sign of OCD as I have to constantly wash my hands or turn on and off the lights. I also feel even more depressed and lonely at night than in the daytime for some reason. Do I just make new friends?
