Newly diagnosed, but coping at age 80

I was diagnosed 6 mo ago by my PCP while at a visit for my husband, age 82. We have been married 63 yr.this month. My Dr noticed my gait was indicative of PD & would explain recent complaints I'd had. He ordered MRI of brain consult with neurologist. I am retired RN, understood where this was headed. I have main issue with mobility, notably falling. 4 major falls past year resulting in chipped rt elbow.
I have some minor problems with writing, keep getting small & very crab like. I have problems reading my own grocery lists! My hands can't grip, or turn things very well, etc. I have learned to be very cautious ambulatory in house. Have cat that likes to do the "zig-zag" dance. He zigs, I zag! Works well. I have a history of osteoarthritis, family disease, also a strong family history of PD. My paternal grandfather died in 1970's, unable to swallow, couldn't tolerate new drug of Sinemet. My paternal uncle also had, but died after pulmonary surgery. My 62 yr old son was diagnosed 3 yr ago with tremors. I don't have that, 11 years ago I had spinal fusion L-1 to T-11 for spondylolethesis. After years of "conservative " treatment this has been a complete success. So all the problems that have surfaced since haven't been explained. I was actually happy to have a diagnosis, I cope much better knowing what I'm dealing with. I do take antidepressant, plus other meds for muscle cramps, OA . We have been square dancing for over 60 years off & on, had to stop while dealing with back-leg pain, but were going 3x week until pandemic, starting up again. I manage to keep dancing as we touch hands so much restores my balance. I plan to keep going until I can't.
I have told all about PD, I want everyone aware so they know I have problems, plus increased awareness of disease. I'm SO grateful that I am 80 when diagnosed, I don't feel like I've been cheated, I've lived a long very satisfying life, it's not over! I have my "days of stones" but many more are days of"diamonds", because I keep telling myself they are! Also have 3 kids, 7 grands & 12 great grands.
Thank you for reading my story , don't give up! Wanda
