Had wrong date wrote down but then seen the change just now

I am stupid for entering this way too late plus when I did not have a ton of money. I got some rewards but then the lp for usdx went down so I kept it in shares in eth/ usdx and checked rewards so often hoping I made enough to even cover gas by the end of mining which I was but now the rewards are gone and I can not withdrawl. Which I ran into the change after the initial panic so am I screwed? I mean can I at least salvage the lp tokens?
