That letter isn't a letter I intend to send. That letter was just a stream of feelings I have at the moment. I am entitled to those feelings and this should be a safe place to write them down.
I am actively suffering from my last visit with her and I needed to write down those feelings and get them out. This is the way I feel. Yes, at the moment it is scathing.
Dear Mom,
I need a mom. Not a selfish drunk/drug addict. No, I cannot tell you what I need for my life because every time I have tried, those requests fall on deaf ears. You are not interested in my needs. You are only interested in one thing and that is what you need to satisfy your addictions.
