Please help! I can’t shower!

I’m dealing with low water pressure since the storm. All neighbors (water flow) are back to normal but not me.

Basically I’m worried the cold caused a break in a pipe that is not in plain sight and I don’t know how to find that out. I really need some help.

How do I inspect the pipes in the attic (or anywhere else) to see if there is a leak somewhere out of plain sight? I’ve checked under sinks and exterior perimeter of house.

Note: I’ve cleaned/removed all my aerators

There is sediment coming out of the bathtub faucet. Water flow is reduced at all faucets to a medium trickle. I have galvanized pipes. Live in Houston Texas house built in the 60’s

Im grateful for any guidance you have.
