I encourage you to keep at it. Awhile ago I decided it was time to get back into IC for a bit. Even for someone who navigates the system as a job (me), it can be frustrating. I went down my list of ICs in the area, left a ton of messages, spoke to some people who either weren't taking new patients or specialized in something or another that didn't pertain to my situation, etc.
Finally, about the 12th person I called, I hit the jackpot. She was really good and helped me a lot.
I'm sorry this is such a struggle for you. It shouldn't be. Don't you think if someone is reaching out for help they should be able to get it easily? Me, too!!!
Keep going, you'll get there.
