Can you please help?

I’m asking for help for my girlfriend, Christine.  She’s had acute shoulder & arm pain on and off since May, 2013. This landed her in the ER once and urgent care 5 times. Recently she had to get 4 steroid injections directly into her shoulder muscle. After insurance paid, she still owes $2,350, bringing her total outstanding medical bills to $4,500.  Additionally, She’s behind in her mortgage payments & needs to get caught up or she will lose her home. She’s lived in her home for 15 years & I don’t want to see her lose it. I hope to move in with her sometime soon, help her with her bills & split expenses.  Thank you for help!
