You know what? You’re not a terrible person! What you are feeling is completely normal, especially if you have gone though an abortion or miscarriage.
You need to deal with whatever guilt or hurt you have inside of you, because nothing else is going to make it go away and you will just feel worse about yourself when the alcohol wears off.
I don’t know if you are a Christian or not, but Jesus can free you from your hurt or guilt, and He is the only one and the only thing that can.
