Pets can be very loving unconditionally. It does not matter the day or mood you are in. They are happy to see you just the way you are. I have a cat and we have our morning ritual. We play together then she sits on my lap for awhile and she also watches me get ready for the day. She knows when I am not doing good and I am depressed or have anxiety. She comforts me and stays close by me. So it just helps me when I live alone to have a pet to come home to.
