$12,345 · looking for dog or puppy for free

I am looking for a dog or puppy that will help with my anxiety, hopefully calm and happy with lots of cuddles. I live in a house and have a big backyard, I am on disability and have mental health issues(I am stable and on medication). I live with my mother and boyfriend. I am always home and need a companion to help me go out and be more social, I have agoraphobia ( afraid to leave house) and a dog would help me to be more calm, especially when I go out alone. If anyone has a friend who needs to rehome a dog, or a puppy, please send them my way. Thank you.
