>I think becoming serious about life has made me put tremendous pressure on myself and that's the reason why my speech impediment has become bad. Let's remind ourselves here of that famous adage of many internet conversations: - Correlation does not equal causation. - Specifically, in your case, were we to make the point that you wanting to concern yourself with more serious things than you did when you were a kid _caused_ your stutter to worsen, we'd be remiss if we didn't point out that you've no way of telling that, given the way things are. In general, kids have less to worry about. When we grow up, more stuff enters and becomes relevant, that we have to deal with. It's not like you're willing yourself to age and arrive at the typical milestones of a person entering life at large, beyond childhood and school. But yes, perception plays a role: If you think it's your fault that you stutter, this is likely to influence the way your stutter operates. So don't think it's your fault. Whether or not there's a direct connection between "being more concerned about things in general" and "losing fluency percentages", this is never something you should blame yourself for. Just focus on achieving what you want, saying what you want and not minding the stutter. It's just a stutter. Some people have that.
