Probably is specific to the person, but my pets are as helpful, if not more helpful, than my therapist. I have a dog and a cat, and I've previously had rats. My dog is unwaveringly loyal and always approves of me, even when he shouldn't (like when I've been super depressed and haven't bathed for a week). While my cat can be disapproving and glare, he is always affectionate and doesn't hold a grudge when I take him to the vet or have to give him yucky medicine, etc. Whenever I'm feeling really down, alone - as well as happy, I like to spend time with them playing and spoiling them. I find making them happy ends up putting a smile on my face, even if it's only for a little while. When I'm really hurting badly, cuddling helps soothe me so that I can calm down and regroup. I close my eyes and lie with them, stroking their fur and focusing on how extremely soft my cat is or on how my chihuahua molds himself perfectly around my head when I'm upset.
