My 4 year old sons mother is in the hospital..

My ex and I split up about a year and a half ago. We have 50/50 custody. Anyways, she was working today and had our son with her. She passed out and got rushed to the hospital. She is on a ventilator and in a medically induced coma. Apparently she overdosed on Xanax and methadone. I had to pick my son up at her work and then I stopped at her sisters and let her know. I am at home with my son and her family is at the hospital. I am so unbelievably mad and sad for our son..the fact that she did this around him. In the 8 or 9 years we were together she never had a history of drug use but I dont really know who she sees or hangs with now. I am definitely not sending him with her anymore if she pulls through, and she has put me through so much hell over the past few years that I don't even care if she does. I feel horrible saying that but all of my sadness is for my son..I don't carer about her at all at this point. What the hell do I do? My son is fine and playing and watching a movie but I don't know what to even say or do when he starts asking about her inevitably. They dont even know how bad she is until tomorrow when they try to see if she can breathe on her own. My parents and her sisters all support me I am just so lost though..this is more venting so I am sorry if this is the wrong sub. Thank you. via /r/Parenting http://ift.tt/2gIJB3W
