Bought crypto years ago, and don’t know how to report to taxes because I used so many diff exchanges, etc

I feel like I’m stuck in a never ending hell. I want to report my crypto, but can’t. I used so many different exchanges, so many different transactions, trading constantly from coin to coin, it’s come to the point where I can’t handle the thought of it.I can’t go back and find them all. I can’t tell you how I ended up with .xxx of this or that. Literally impossible for me.What do I do?I am scared if I decide to sell I’m causing hell for me financially for my taxes.I don’t know what to do.EDIT: For others, the advice from the comments below seem to be either, try and go back and get the records and use bitcoin.tax to try and create a cost basic so I can report. Also, another option is to pretty much say your cost basic was $0 and your profits are whatever they are. You'd be paying the full amount, but, no worries there, you'd be paying the max.EDIT: Question though, a lot of the responses are great but what about the fact that my trades are from years ago, like, do I amend older taxes, or report now on 2020 taxes if I sell this year?
