Despite my stance on addiction, I think that it's quite wonderful that you are calm. I am a high key person with a high anxiety level. It has taken me YEARS of therapy and support to get to the point that I am not carrying around a million tons of anger and resentment. That hurts one person, and it is me.
I don't believe substance abuse of any kind is a pass for bad behavior. I also know each person has to make their own choices for what they will and will not tolerate. I think when so many have went through the heart aches we collectively have as a group, you want so badly for not one more person to have to experience those same aches. However, just like anyone, you cannot control anyone else's actions, only your own reactions.
I am glad you are in good care physically and that you have a calm emotional state. That is excellent for both you and baby.
