I new help on a bnsc network on metamask

hi, i recently created a binance smart chain in a metmask network, and i deposit 80 doges in order to swap them to bake coin, the problem is that i also charged BNB for the fees but everytime i try to swap it, it would not let me do it, and then i wanted to withdraw my doge coins back to my binance smart chain wallet, it would not let me do that also, it just appears in the activity box but the transaccion never succeed, if you could help me i would appreciate it, thank you.
