Help me save my home

I’m 22 years old, I bought this home with someone else when I was 20, circumstances have changed, I need to come up with 11k asap while I’m still paying my current mortgage. Otherwise I’m going to have to sell my home, which at this time I will walk out with nothing, I have 2 dogs who live at my home with me, a golden retriever and a Labrador, it is so hard to find more homes to have dogs and I don’t know if I will have the opportunity to own a house by myself again, you can please help a little. I appreciate any help given to help with my situation.
