yes, marriage is one option. It may lead to your leaving baseball and this problem will be cured!
There are lots of things you can do. I’ll just start by saying you can’t block something out directly.
Don’t think of a pink elephant. Or a red slipper. Or giving up a HR.
I said DON"T think of those things.
The only way to “block something out” is to get so into something else. When you are pitching great you are so into the target the rest of the noise goes away.
You can practice this simply by reading or stareing at something when there are distractions in the room. Focus on an object for 10 each day.
This is a big topic and I’ll return to it later.
