New Diagnose

Hello. Three years ago while hanging Christmas lights I noticed my left hand was slightly shaking when using hand tools. I ignored it for two years, three months ago my right hand showed minor symptoms. Diagnosis essential Tremor. When I exhaused all meds for essential tremor, they tested for parkinsons, and I tested positive. At this moment I am reducing the essential Tremor drugs, will start Parkinsons drugs in two weeks. I am at a loss to know what options might be available or next steps. I am 70, retired with a part time job, and do not have the financial resources I think I need. At least the Parkinson drug is cheap. I live in a desert, not a lot options. Saw this site and decided to post the question as to what options are available to me. Thank You.
