Does the sound "sssss" 'trigger' you? Please read description 💕

The sound 's' irritates me. It always has. When I was a younger child I would have frequent outbursts because somebody talking would make a "too sharp s" as I call it. Now I try to suppress my anger by grinding my teeth or making the sound back or leaving when I can. It's such an irritating irritant to have because it's so frequent. It's not something I can avoid unless I avoid people in general. I have no idea what's wrong with me. I kinda always thought of it as OCD but with the alphabet if that makes any sense. Does anybody know of any conditions that relate to this or have any stories I can relate to? Person tips and tricks on remaining calm are also much appreciated 💕💕
