I have been divorced for 7 years. We have 2 grown daughters.

I have been divorced for 7 years. We have 2 grown daughters. The youngest is near 26 years old. She was diagnosed in grade 8 as having cognitive learning difficulties. She was also ADHD. She had been and remained in private schools that had small classes and
one on one. She got into drugs and trouble with the law in 2004 and then came our divorce. While living with me both girls attended college but the youngest quit twice.
Over the next 5 years I supported her living at home and helping her. She went to the States twice for Rehab but her drug use became worse. I asked her father many times to help me with her medical/living expenses. He refused and continued to bully both of us.
She is now bipolar/boarder personality disorder, opiate addict and on Ont Disibility for depression. I continue to finically support her as she is a kind young woman who has mental illness and I am a mother who loves her children. She always wanted her fathers love but he has verbally abused her since a child and continues to put her down, and me whenever I ask for support and kindness for her.
This is a brief outline. I myself have become burdened with health and finances because of caring for her and now need help. I need to get a lawyer who will fight my ex to pay
for his daughters future care. A lawyer who will help to get me some of the monies payed out when caring for her, payed back. This is about my daughter and what is the responsibility of parents with a ill child. About her human right born our daughter.
Please advise the type of lawyer I need.
