This is one of the reasons that we exist. Venting and having another ear to listen to us is one of the most therapeutic things that there is!!
I can offer up something that I'm wondering about in reading your 'vent' ...how much are you on the phone with these other Dr.'s and their nurses getting on them about these needed appts.? In today's world I'm sorry to say that it's no longer the Dr. that calls you at home and worries about you and sets up all your appts (they do worry, but they don't have the convenience of time anymore). You may get some help, but what I've found during the last 30 yrs. (and increasingly so), is that we ourselves need to be a part of our own health team and not only rely on our Dr.'s, but to pick up the phone and start making some of these calls ourself.
You are now the receptionist and secretary for your health team!! You must follow up on what Dr.'s tell you to do, whether it's something that they've mentioned doing, or planned on doing...you need to handle your own insurance companies at times to make sure that they are paying what they should be paying.
I wish you the very best, Bee, and please make sure you continue to come here-if only to vent, or ask questions, or offer support to some of the others going through the same things-you are very welcome here!!
Big Hugs, Teri
