not a lesbian question

I'm a heterosexual sister but I need sisterly advice please..of something off the topic here .....i recently kicked out my 22 year old daughter from my home...she has a 9 month old son..my grandson.....i raised my daughter as a single parent and took care of here since i had her at 17 her father wanted absolutely nothing to do with her...now when she lived with me it was rent free as she was trying to go to college and make something of herself so i supported her and did not charge her any rent when she got pregnant I went  to appointments with her, comforting her when she was crying over the father, and feeding her when she was hungry, and the baby father he wanted nothing to do with her or the baby and still to this day has really nothing to do with the baby. His mother (the other grandmother) also did not want my daughter to have the baby and tried to do everything in her power to get my daughter and I convinced to make her abort her pregnancy.  Now because the baby is all light skin the other grandmother is going crazy (they are color-struck), and my daughter feels she doesn't need me now because her baby will have another grandmother whether i'm there or not.  So she began to be outright disrespectful to me, and so after enough disrespect I threw her out.  She went to live with my sister who cursed me out and began to talk very negatively about me to my daughter.  My daughter told me I was DEAD in her life and that I seriously needed help because I was evil and crazy.  Now she's told me I could not see my grandson until I learn to respect her.  I've never drank or did drugs and I must lnow earn to "Respect" her or I can't see my grandson.  Any advice as I'm in serious pain?  I feel like I tried to do my best by my daughter and my best wasn't good enough and as long as my sister negatively impacts my daughter's brains she will continue have hatred towards me....
