My last pregnancy

i was so wrong for what i did. I found out i was pregnant last january. I knew i was pregnant and i continued to drink. I drank all of my second and third month. My fifth month. I was drinking vodka everyday and smoking ciggaretts. I did heroin five times and meth one time. During the last three months of pregnancy i used vicodin, some klonopin, some flexaril. I feel horrible about all of this. No one knows about ALL of these things. Some people know about the alcohol and smokes. But not how much i really was doing. I was not taking any mental health medicines and i was pretty much self medicating. I never once drank or did anything with my first son. I feel so bad for my baby. I do not know if he has any affects yet but maybe they will show up later. I just want him to be healthy and have all the benefits all children have without me causing him to have a poor life.
