Stutter so bad to the point I want to go mute

Stutter so bad to the point I want to go mute Hi, I’m 20 and have a pretty severe stutter. I work in the horse training industry. I got a call today from a ranch looking to hire me. I declined the phone call because I didn’t want to sound “stupid.” Honestly it’s getting to the point where I’m considering going completely mute and just not speaking. Also considering leaving my career and just doing something else because I’d rather just not speak it’s that bad. Has anyone ever actually tried this or have a similar experience?
