Hi, and welcome to NT! I'm so sorry for all you've been through.
Here is a link to the Service Dog forum:

I have MS, and I have a service dog. His name is Monty, and we've been partners for over three years. There is a website:
AssistanceDogsInternational.org They will be able to provide you a list, by state that will tell you where to find a trainer who will work with you so that You can get Bear certified.
Good luck to you!
