About a month later I still had not heard anything so I sent an email to them inquiring about my status. They said my membership was declined and gave no reason and never responded when I asked why.

I attempted to join again from my secondary email with no response from them. The group appears to be a sham and doesn't even accept anyone. I find it rather hurtful that either someone would create a false support group and reject everyone that wants to join. Or if it is a real group, I find it hurtful that they reject members that truely have pain without even giving them a chance.
