The only friend I have is four legged. My cat, Sweet Pea. She loves me unconditionally. I don't have to look a certain way or act a certain way. She accepts me and my PTSD, anxiety and depressioin. Had I known how great animals were years ago, I would have never gotten "married" or even thought about having friends. As soon as you tell someone you suffer with depression, they look at you as if you come from another planet and that's pretty much the last you'll see of them. So, zero human friends, one great, true friend.
