Internal medicine: I would see a general medicine internist who can confirm, prioritize, treat, and if necessary, refer you to specialist colleagues. Complex care is what internists do.

Family physician: Find a family physician in your neighborhood , current fp s are highly trained , they are friendly , have all the skills you are looking , they will give all the time to discuss your problems, always available if you need they know the right specialist to refer you.
