I'm in a pickle

Hi all,

I misplaced my seed phrase where others could have seen it. I have the phrase still. I have stacks that come in from my original investment still. I’m guessing I should open a new wallet, but how do I change where those original stacks go? Also, is there way to protect myself further?

Sorry if this isn’t the place to ask this, but couldn’t a find a place for other support.
