Pets are really amazing and it is hard for people to understand if they have never had one. Growing up, my dog was easily my best friend and the best part of my family. I was devastated when I lost her because she was the only one in my family I could rely on to always be there.
Last year when I was really depressed I adopted my cat and he changed my life. I didn't spend a dime for him at the shelter (well, they charged me $5 for a cardboard box to take him home in) but he drastically improved the quality of my life.
I'm glad things are starting to make sense for you and come together!! Just know that you're not alone in the way you feel about your pets
