Was Denied DAC Benefits But Fit The Criteria

I'm so scared now and I don't know what to do...they said they got my records from my doctors EXCEPT from my mental health clinic (not sure why that happened, but they said they did not hear back from them).

I have been on SSI disability since my 18th birthday and I am 44 yearts old now...my FAther retired and I was told I had to apply for DAC because he retired...my disability started in childhood BEFORE my 18th birthday (well before age 22).

So why would they deny me? If I am denied on this but have been on SSI since age 18 and with each review they say I meet their rules for SSI, why would they say the opposite for DAC?

Am I now kicked off of SSI as well because of this? I'm very scared and my anxiety and OCD is really intense right now. Why is this happening? It is not like I all of a sudden applied for any disability out of nowhere at age 44.

I feel more confused now than anything else about this process and the workers.

What does this all mean now? Please someone that works with the program help to educate me.

Thanks.
