I have a cat, two dogs, and a bird (my brother's). Though I have not been diagnosed with anything (I don't want to be), they help me when I am anxiety ridden or depressed. My cat won't leave me alone and makes me pay attention to him when I am crying or depressed and my dog will jump on me while I'm sitting and apply slight pressure to help ground me. He is very well-trained in obedience, so when he does this, it first seemed out of character, but we caught on fast. They also help me in public with talking to people and staying calm. They are trained to the level of service dogs but I won't use them as one since I don't want to be diagnosed with anything. I could never leave them behind, no matter how hard life gets.
