I would love to hear more about how to focus oxygen on ones frontal lobes. I am familiar with CBT. I posted my story here, but I can't seem to find it tonight. I did begin singing with tapes again and listening to music more often, both recommended on this site. The singing and staying focused on the lyrics has been a shock! I kept being distracted by other thoughts. I had no idea it was that severe. But I just start over and it truly is helping. I have speech problems, wrong word, mispronounce, slight stutter, etc. The singing also comforts me and decreases my anxiety. If I am tired, hungry, or have to drive in traffic, my speech is worse. The day after my injury, my speech made no sense at all, so many wrong words. I am greatful for all of you.
