You may not get this job, and that's ok. I understand you feeling bummed out right now. I'm also sure the person you talked to will remember the most brave candidate they had all day. As stutters some things in life ida harder, but we need to do them anyway, and when we do it people understand what fighters we need to be. Who doesn't want to hire a brave fighter? Maybe not the once you talked to today, but that's their loss. Keep it up, try to be the best version of you, for you. The rest will work out.
