I'm unable to receive certain text and I'm not sure as to why it's happening. I no longer receive my messaging like appointment reminders, dates, time

If you can't send or receive messages on your iPhone, iPad, or iPod touch - Apple Support

I'd also make sure to check that Do Not Disturb is not enabled. Check out the article Use Do Not Disturb on your iPhone, iPad, and iPod touch.
