What Happened to Medicine?

I am dismayed at the medical treatment, or lack thereof, that I have received to date. I sent an online message to my PCP a few weeks ago that I was feeling hopeless and depressed as a result of my illness and asked if he thought increasing my antidepressant would be of help. He did not respond. I have to see him next week and will ask what the purpose of the online message system is if a patient cannot get a response from their doctor.
I understand that my condition(s) are complicated, after all it has taken 3 years to finally get an appointment with a liver specialist, even though I had been told one would never see me. I apologize if I sound like I am whining, perhaps I am simply frustrated at just how difficult it is to receive the appropriate medical treatment these days. I try to remain positive, active, engaged in creative activities and things of that nature. I am not curled up in a ball in some kind of catatonic state. All I want is help from my medical team, and it has become such a struggle to get the treatment I think I need. Yes, I have a friend who is a doctor and who has been very helpful by telling me what tests my PCP needs to order, and when I ask him to order such tests he does. but really, how crazy is that? This forum and my disease have enabled me to become more empowered, however I had no idea that getting the right treatment, if any, would be such a struggle. I have good coping skills, but in all honesty there are days when I really do feel like curling up in a ball, but I don't because I am afraid I would remain in that state. So instead I take walks, work on my artwork, bake bread for my neighbors, care for my 84 year old friend etc. I am constantly on the move. Right now, I just want to step off and rest.
Also, the last time I saw my PCP he asked me if I wanted a new doctor. No doctor has ever asked this question of me. I am now planning to choose a new PCP after my upcoming appointment with a hepatologist. I am seeing my PCP this week so he can go over with me the information he received from the hematologist regarding my immunoglobulin disorder.
Interestingly enough, I met with a neurologist this week for the second time. I could not have asked for a nicer physician! Perhaps there are still medical providers out there who still care about and want to help their patients.
