My iPhone screen is not responding? - 1

It was cracked before very badly and I'm not sure if something got behind the screen because of how bad its cracked or if it's because of the cracks themselves or something completely different. Also, the day it did that I played music in the bathroom while showering and it was very steamy bc no fan in there, and it was slightly wet. Is that why?

Depending on how deep and open the cracks are on the screen, the steam from your shower could have damaged your phone. It also depends on the time you took in the shower (A short shower will not really cause this, but the longer your shower, the more water can form on the screen)

Of course, the shower scenario is only one of the possible ways the phone could have broke, so it's only a possibility… (Water precipitates from shower -> steam lands on the screen of the phone -> screen gets wet and water can seep into the cracks -> Phone can malfunction or break.)

Otherwise, do you carry your phone in your pocket or bag? If you have other items with it or move in a way where the phone can bend or is stricken by something, it can also cause some damage. Or the screen could have just finally gave out, it happens.

My only recommendation is to try to reset your iPhone by holding the power button and home button for 10 seconds and let go as soon as your iPhone turns black and shows the Apple logo again. Otherwise, I think it's time to get a new phone.
