Man, sounds like you got a lot of other questions in life besides just your bike. Just curious, what's causing you to want to take the bike to a shop? Is it because its just routine maintenance or is there a major problem that you're dealing with? If its a major major problem, might be best to find a reputable bike shop to diagnose and repair. Otherwise for standard routine maintenance, you should be perfectly fine.
Now a days, there are so many alternative ways to get around if you don't have your bike. Not sure where you live but there are those electronic scooters by lyft and lime that you can use to get around. Obviously public transportation like bus and metro. Or worst case if you need, just call Uber for a ride.
I think you're overthinking it too much.
