Thanks milli,
I am happy to hear that you are receiving support. I don't have a concussion clinic nearby however I do have 4 people on my support team that help me including my doctor and therapist specializing in different areas. All of them show a great deal of compassion and understanding for which I am grateful.
Accepting this new reality is the hardest and it takes time. I can see you are doing all the right things. How much time depends on how much we grieve and let go of the "normal" life we led before. I have found that even when I reach a point of acceptance, I sometimes think about how much I want to run or workout at the gym and then I cry a bit more.
Can I ask what the speech therapist is doing to help you? This is a field that I've grown very interested in over the years and have thought about studying.
Take care and good luck to you too
