When I get a cup from the cupboard I fill it with tap water & microwave it 2 minutes to heat the cup to nice and toasty. Then dump the water & add the coffee. The coffee is brewing while I do this, so no time is wasted.
I never think to check for spiders, but if you try my idea you’ll get rid of spiders, roach poop, gnats, and other assorted nasties automatically.
I can hear that you have a promising career as an artist. A painter perhaps? Or maybe sculpture will be your forte. 
TBIs are bad. But simply getting old does the same. You got a literal crash course in being elderly before your time.
I don’t say that to minimize your injury. But to point out that for each of us older folks (except Cookie) there is a trap in your current living arrangements. You can’t be 90, living alone, and still maintain that big now-old house full of crap. The risk is you become too lazy / infirm / senile / whatever and the job becomes bigger than you are while you’re not looking. Then you’re trapped in a rest-of-life sentence of living badly in inappropriate and perhaps even squalid circumstances. Which is probably unnecessary.
The esteemed ThelmaLou wrote a beautiful OP that became a beautiful thread about the effort and courage to move to simpler safer surroundings before it becomes impossible. Rather than succumb to wishful thinking and inertia until the trap is sprung on you. That OP also has a link to a “one year later” thread that’s worth reading.
