stressing out for induction day on Monday

stressing out for induction day on Monday its a couple days away and im already overthinking and stressing out about what to do. My stutter is so bad and severe whenever I'm under pressure or speaking to new people. I'll mostly avoid trigger words which are technically most words that come out of my mouth but if I'm comfortable with someone then it reduces quite abit. No one really knows I stutter because I hide it so well, ppl just think I'm shy or mute xd. Do i really have to go? any advice would help.
