How do I recover Safari tabs that disappeared from history on iPhone?

safari closed all my tabs on my iPhone. I did not close them they are all just gone. I held the thing to reopen closed tabs but it only shows the last tabs that I had closed yesterday. None of the ones that disappeared on their own. I cannot get them back by searching through my history bc they’re from several months back. Stuff I was in the process of reading and waiting for updates or websites I was watching for info. Is there a way to get them back? I need them. I don’t think I’ll be able to find all the ones I was following for updates on my own.

Original Title: Safari closed tabs. They don’t show up on recently closed. Can’t find in history bc they’re old. I did not close the tabs.
