Need real advice ladies!

Shamya

So long story short, my mom was addicted to drugs which messed with her mental health and she is also anorexic. In the 5th grade i was put into foster care and lost all contact with my mom. Dad was an abusive prick who was sexually, physically, and mentally abusive to my mother, my brother, and myself. Fast forward to when i turned 15 and got adopted. Then i turned 18 met the love of my life and got married. I got back into contact with my biological mom at 18 and realized how much she has deteriorated over the years. Talked to hubby and she moved in with us. Now i am seriously hating myself for helping out. She no longer does drugs but her hygiene sucks. She cant hold her bladder and ended up peeing on our brand new couch and hiding it from us. She still looks at me like im 3 years old and is always telling me how to do stuff and is trying to help around the house but ends up pissing me off more than anything. Don't start with the hateful comments because i know how horrible it sounds. How do i handle such a hard situation. Since she has lived with us she is now talking about staying with us until she dies but we are ttc and she is just added stress. I dont want to kick her out but it seems like the only option.

Sorry it was so long but any help or advice is appreciated!!!!
