I made a mistake. Perhaps someone can help.

I dont usually deal with etherium at all. I usually buy xlm on coinbase/pro and send it where ever I need to purchase whatever I am after. Well I wasnt in my right mind last night and I bought usdt and then sent it to metamask. Because I dont have any eth to pay the gas fee's its basically stuck there as far as I know. It isnt a lot of money (100$). Is there anyway I can get it off or converted to something else with out getting ate up with fee's?
