Hi, Portster 1987 --
Try not to worry during your four-week wait. The medications for PD (if that is your final diagnosis) are very effective for most people. Although I didn't experience depression, I had the lack of arm swing, awkward gait, and typical poor posture prior to taking any meds. My right side, particularly my hand, could not keep up with my left side in anything. When I washed my hands, the left hand did all the work. When I played the piano, the melody disappeared.
But for over 20 years now I have been taking PD medications, and people who meet me usually do not guess I have any disability. If you find the right combination of pills, most of the symptoms can be counteracted, at least for a time. Although I am aware of my illness every day, it has not changed my life in a very big way.
Good luck with your appointment.
