That totally sucks. I despise condescending people. Do you think it would make a difference to send a follow up letter to the committee and explain that you were being triggered by (disclose if you choose) during that meeting and felt unable to respond in a manner to discuss your concerns at that time? But now that you have had time to process it you find the committee's decision unsuitable because <insert reasons>. What is there to lose? Waiting two years for ten sessions fails to meet your needs. Putting all this on paper may be cathartic and if there is a higher up person that you can cc a copy to all the better.
