Live in slave

So this comes out of my dad’s mouth….”isn’t this why you are here?” Some times, I swear, I just want to leave! Yes, I have come to help them, but be very careful, I am not your slave!  My dad is 88 yrs old and wants to work on his car, mind you, that means he’ll tell me what to do and I do it. Which I don’t mind once in a while but the more I say ok the more he wants me to do. It’s like Brenda you should not have a life you should only do what we want you to do. My brother who has lived with them off and on for many years now (and who takes care of everything outside of the house) has warned me…”once you give in a little bit they will try to suck the life out of you”.  My dad literally will throw a fit, going on and on how no one loves him or believes he is worth something. This is so emotionally exhausting sometimes!
