Struggling with a friend and circumstances and health

Hello and thank you, I’m struggling with a friend who has pretended to be a christian for 15 years but keeps screwing me over and I keep bailing this person out, picking up all the pieces and they don’t care what they’re doing to me. Im also homeless and taking care of this person their three cats and their home and I am struggling and wake up every day feeling heart broken and overwhelmed. I simply cannot cope anymore and it affects how I view Jesus. Please pray that God breaks through to my friend because I know they won’t change and they don’t care how they’re affecting me.Thank you sincerely!
