Welcome! You have made a big step already by deciding to come here and look for support. The suggestions for attending meetings are great. It is overwhelming at first, but the support that you can find can help you to find your way. Take care of you. It is great that your husband is getting help and moving along. So much loss in such a short period of time... I am sure his world was rocked. Hopefully, he has found the light and will stay clean.
Keep coming back here. There lots of us who are here to help and to share... and you will learn how much your thoughts help everyone else. Go hug the baby! HUGS to you!
