I have to attend this sports team tomorrow and I can’t even say my name

I have to attend this sports team tomorrow and I can’t even say my name So I’m a 19 F second year college student, I had mild stutter first year ( had severe stutter through my life since childhood) , managed to get away with introducing myself after someone asks me my name , I would say It’s “ my name “, my name starts with an M but when I say it’s, I co-join my name with sss sound from its . Idk how I managed in 1st year. But yeah I did . Now my stutter has increased a lot idk why , even talking to my frnds is a hard task. Tomorrow I have to join this football team and obviously have to introduce myself , I cannot just go and be like it’s” my name “ , I cannot say I AM or MY name is both of them cause me. To stutter , only it’s” my name “ doesn’t . What should I do? Do I have to join the team or else slide this off . But there’ll be many situations like this in future, idk how I’ll manage with Its”my name “. Any tips ? Or advice ?
