I stuttered in a job interview today - should I withdraw my application?

I stuttered in a job interview today - should I withdraw my application? The last few interviews I’ve had, I’ve managed to keep the stuttering down, but it was so much harder today I have a bad feeling it didn’t go my way because of the stuttering and because they said right at the end “you were our last interview and we’ll have a decision by tomorrow, but if you’re not successful, please do look out for other opportunities with us” Should I withdraw my application first thing tomorrow to avoid disappointment? That last line from them got me down and the stuttering was noticeable Please advise fellow stutterers. I have no idea what to do
