What do we do when doctors ignore our symptoms, even when they show up in lab work?

I’ve had years of labs randomly coming back irregular but seem to not cause red flags, despite the pain and other symptoms I display.
I understand that doctors are exhausted, there’s shortages, etc. But I don’t know how to diagnose myself. And the doctors that take the time for me seem to be also mystified by what comes up.  All agree I need to see certain specialists but yet can’t seem to get those specialists to put me on their calendars.

Things have become so bad that my children have both asked me if I’m dying. While I’m reassuring them that I’ll be okay, I honestly don’t know if I will be with the lack of knowledge of my health.
