Yea man, I used to.
If you're at a noisy place sadly there isn't much to do.
What you can do if you can is buying acoustic stuff to help, if you can't afford a acoustic window, curtains are a great deal for cheap price.
This is a last and unpleasant resource, that should be used only if nothing works and your hyperacusis isn't better; sleeping with ear muffs.
I don't know if your h is loudness or pain or how severe it is, but if you're at that situation because of a setback, time might help most of times.
