223 usdt lost

So i used to be planning on swapping some ethereum for ustc, as they are planning their repeg program, so i deposited ethereum to my metamask pockets, and from there i exchanged it to tether usdt, and when i attempted swapping tether to ustc it stated that there was insufficient liquidity, and i noticed this was as a result of i used to be on the ethereum community. so then i'm going to bridge, and i bridge all 223 usdt from the ethereum network to the bsc community, and then it says that its confirmed, so then i change networks on pancakeswap, and to my disappointment it stated that i had no tether. i then switched again to the ethereum community to see if perhaps my tether was nonetheless there however it wasnt. i even opened up my metamask pockets and checked and to my dismay, there isn't a stability. is there one thing im doing incorrect right here or is my usdt ceaselessly lost?
