Please don't be mean or judgmental ....::: hopefully someone on here can be helpful ?

I am prescribed methadone for substance abuse, I have been on it for a year and 9 months ! I am 8 months and 3 weeks pregnant  , I want to breastfeed but not sure if I can while being on this medication ?? Please don't think badly of me I have hurt so bad over being on this medication while pregnant ! I absolutely hate the idea of my baby suffering after she is born and hate myself for being in the situation I am in but I wouldn't change anything other than not being able to come off the medication pregnant my doctors won't allow me to but I was able to talk them into letting me lower my doae ! My husband tries to reasures that I am on the medication to better myself and my family and that everything will be alright but he has never had a substance problem the worse thing he has ever done is smoke a cigarette ! But to have his support is very comforting !! If anyone knows anything about methadone and breastfeeding or is it has been threw this please help can I at least breastfeed my baby the first couple days or is there a miracle out there that I can clean my breast milk with so she can breast feed until she cannot be breastfed anymore ?? And please no mean or hurtful comments I feel awful enough !! I am sober and on the medication for my children and my family my sobriety is very important to my husband , my family and myself  !!!!!!! Please help if anyone can.
