adult daughter driving me crazy!

[lv3313]

My daughter is 41 a single mom of 2 boys age 11 and 5.
She depends on me for everything that goes wrong in her life. I have helped her raise the oldest boy, of course, he and his mom do not get along. I have given her a place to live in my mom's house and she only has to pay for the utilities, She calls me everytime something goes wrong, even discipline with the boys and then the oldes calls me crying about his mom. And now on top of all this, she was diagnosed with breast cancer in Dec. and I have helped her through Chemo( she's actually doing good) and now comes radiation/ Because I have done so much for her, I have caused problems with the other siblings and my husband as well, who is her stepfather..I don't know how I make her understand I have had enough and she needs to grow up and take on the responsibilites for herself. Any suggestions out there???
