hope you keep us posted about your individual situation. you never know when someone on this board maybe able to help. as you can tell i am the eternal optimist. don't want to exacerbate your situation or pry. cohort 5 might still be open. good luck.
Best wishes to you ... I have friends who have been "inoperable" for years, one for more than 5 years. Much progress has been made and there is more to come.
