I've Been Diagnosed With Worsening Anemia And Referred To A

I've been diagnosed with worsening Anemia and referred to a Gastroenterologist but can't get in until July 6th and then only the PA. Is this Dx more urgent and should I move on to another practice ? Also, I'm not absorbing B-12, get an inj once a month and I have indolent lymphoma, among other chronic illnesses. DM-2, diverticulitis, and occasional partial and full bowel obstructions.
