I was using my nicehash BTC wallet address for the pool, do I lose all my work if I change to another wallet?

You don't lose it but it goes to another address which means you don't accumulate as much in one address. If you were below the payout threshold and abandon the address then it will never get paid anything. I highly recommend using one address as much as possible.
Well... Here's to hoping nicehash comes back online. Hate to lose my work because of their misfortune. If not, I guess I'll just have a learning experience.
