We have a well, deep drilled which we did have severe supply problems with in the past due to low production rate. We had it drilled deeper and hydrofractured which seems to have fixed the problem.
You say you think the water pressure goes down. Wells are controlled by a pressure tank/switch which should maintain supply to the house between 30-50psi. (i.e. the well pump will cut in when the pressure drops below 30psi as water is being consumed in the house).
Are you getting less water out of your taps? I'd check (or get someone else to check) the pressure/tank & switch first. Our supply issues seemed to be more prevalent in spring/summer than winter. The well would run dry and we'd ahve to wait for it t refill.

A typical pump well water supply consists of a well, a pipe , a pump, a surge tank, supply pipework and taps.
The supply pipe should be fitted with a non-return valve at the pipe inlet to keep the pipe full.
The pump should be fitted with a an adjustable pressure switch that turns the pump on when the discharge pressure falls to about 30psi and turns the pump off when the discharge pressure is 40-50psi. If the well runs dry, as it did with my daughter, then the pump may run dry and damage itself. We found it would no longer achieve 50psi but would get to 40-45psi. The switch was adjusted to compensate for the lower discharge pressure removing the need to buy a new pump.
The surge tank is a metal cylinder fitted with a pre-pressurised (to about 25psi) flexible plastic membrane separating the water from a pressurised air cavity. It is situated on a branch pipe from the pump outlet. As the pump discharge pressure rises it fills the tank and pressurises the air-side of the captive membrane. In this way it forms a pressurised reservoir of water than can be discharged on demand without having to start the pump. Only when the surge tank empties and the air-side depressurises does the pump need to start refilling the surge tank.
The supply pipework and taps need no description.
If the water pressure falls in winter I'd suggest you investigate the surge tank. If the air-side of the membrane has lost pressure then it should occupy a lower volume in very cold weather and if the pump is operating more frequently than it should this might indicate that the air-side need re-pressuring. I'm not sure but I think these are fitted with simple tire valves to allow recharging and these are located at the top of the tank. A surge tank losing pressure will mean that initially once a tap is opened the pump discharge pressure will fall rapidly to the lower switch pressure and the pump will start refilling the surge tank AND supplying household water simultaneously, doing neither as well as it should.
To test, I'd suggest you flush a toilet whilst looking at the pump. You should be able to get quite a few flushes before the pump starts. If it starts quickly then the chances are that the membrane has failed but try re-pressuring the tank first just in case it hasn't.

Amazon seems to be getting more wasteful. I ordered some household supplies, 6 items in total, the labels all indicate they originated at the same fulfillment center, they were all delivered by the same person. Amazon sent each item in its own box, 6 boxes for 6 items.

Looking on the bright side that's potentially six lots of bubble-wrap to pop.

They use paper for filling now. Havent seen bubble wrap in couple years.

I still get some. I especially like the big ones that you can squeeze two handed. Very satisfying.

I must not order fragile enough items.

Bubble wrap: something for people who don't have a cat.

If you have ever wondered what blue whale poop looked like, now you can. Apparently these whales bowel movement is up to 200 liters worth.
