It is hard. I did not realize how many places in my life it was affecting me. It has gotten much much better with time, and with awareness. If I can keep my whits about me, I can apply that it's not really my rational thinking at that moment, but the PTSD from the past. I have learned to stop and think, sometimes for a long amount of time, before I speak. I am also practicing the breathing techniques my psychiatrist taught me which help more than I could ever imagine. Sounds like something so minor, but it does make a huge difference.
You are doing great. Keep it in perspective that you did not get this overnight, and it will take some time to heal from it. That's absolutely OK because you are growing as a person as you heal, I can tell that just from this board.
