Hi and welcome
I am in a somewhat similar situation as you. My fiance just checked himself into rehab 8 days ago (his DOC painkillers and xanax) and I am due to have our second child the 4th of march and he will be getting out just barely before our little girl is due. It's such a hard situation to be in but please embrace what everyone has to offer on here and take advantage of all the resources that you can, family support, state aid, all of that. It will help more than you could imagine, things like W.I.C and SNAP (food stamps) are fantastic. I learned all of this from when I had my first child. I'm so sorry this is how things are turning out for you with your first child right around the corner and I do hope he does well in treatment but I'm glad you found your way here. It will help you tremdously to have the support here as well. Good luck to you and congratulations!
