I'm scared to tell people at work I (block) stutter.

I'm scared to tell people at work I (block) stutter. First off I'm really grateful for this forum. I have read that it's better to tell people about your stutter than hide it. I have told a few people about my (block) stutter, and they have been ok with it, and it has made it easier talking to them, as I don't have to worry about stuttering as much. I try and hide my blocks as much as possible by word substitution and not talking. I know it's not good to keep hiding my stutter, instead of dealing with it. The thing is that I've been at my job a few years, and I feel like it would be weird to mention it now! Most people probably don't realise I block stutter, but that's only because I hide it as much as possible and avoid situations with make it worse. I'm just worried I tell people at work and they will judge me, or I'll be looked down upon. I feel shame hiding my stutter, and I'd rather tell people, but I'm scared of the consequences. Have others told people at school or work about your stutter? How did they react? This mainly applies to people who block stutter, as other types of stutters are most obvious and you probably don't need to tell people, they can work it out. I hope this doesn't offend anyone! TL;DR I have a block stutter, and I'm scared to tell people at work. Has anyone else dealt with this? Thanks!
