I really hear how overwhelmed you are! I'm a list-maker, you may want to make a list of each doctor and what they are doing for you. Then just prioritize the issues. What health problems are top priority for you?
It would also be helpful to share this list with the docs; so everyone will be on the same path. Also, if you feel you have several doctors duplicating care or services, thin them out! Be an active and informed consumer (it really helps with control issues too!)
