Dan, i've had couple of moments like that where i've thought i'll never see again, or i'll never walk again, but with time, ( lots of time) it gets better. Don't get in a hurry to use power tools, a doctor once told me when you can balance a basketball on your nose than you can get in a car to drive again, that never happened but i did take my time and it all becomes normal, just before the pandemic i went to the same doctor for a check up. His first words were you sure can drive, apparently i've passed him somewhere, small city. Paying someone 1600$ to do a proper job may not be a bad idea, it will put you ahead and let you enjoy it sooner, just make sure that includes all the undercoating every hard to reach and time consuming job.
Best wishes, stay positive. Goce
