It's not your fault. It's too bad your mom had to put you through all that. I don't do it much but I'll reference the bible here. Jesus said "forgive them for they know not what they do" when they were taking his life. so, in this case, work with your T to look at ways you can forgive your mom. She learned that behavior somewhere else ... best thing you can do is not repeat it so you can end the chain.

Height is not a big deal for some entire-cultures. I have known a lot of guys and their kids of Mexican descent and they all are about 5'6" or smaller. Great people, friendly, loving of their families, hard workers, loyal folks. So, your T can help you with the PTSD, pain and forgiveness issues and then hopefully you can see yourself as the beautiful spirit you are rather than your physical body. A good reference is to look at Danny Divito and his wife Rhea Pearlman - both short but great people, very successful and a loving couple.
