Shit, addiction really fucks you up man. Makes me sad to hear you have become a victim of an addiction too. I've personally struggled with Heroin for a long time, completely fucked my life up, I'm still picking up the pieces , I've hurt everyone and everything that ever meant even a little to me. Makes me sad when I look back at it but I guess I deserved it, I'm ashamed of my past self. I'm a bit over 2 years clean now but every single day it scares me to death that I might hurt the handful of people that love me despite all this again.

Do what's best for you and your kid. As much as I hate to say it, when addiction is deep seated, people are beyond saving and no one deserves be sacrificed as collateral damage just because you love that person.
