Hi there blue
I’m sorry to hear of the struggles your facing currently. There is lots of mum’s in the same situation on this forum.
I find myself on the other side, I too am 34 and an addict. In answer to your question from my own experiences of active addiction and being bailed out by my mum on countless occasions you have to refuse to keep paying her drug debt because if she knows there is someone who is going to pay it is like a green light for an addict. Especially someone who can be manipulated emotionally. I know that sounds horrible but it’s the reality. At times during my using I would say I was being threatened and that I needed money to pay a debt but I really needed the money to pay for that days drugs. It’s shameful behaviour but addiction is a changer of everything it comes into contact with
