Emotional issues with kids

You know, when I was in grade 3, i got this lice problem and had some in my hair. I remember this barber, calling another adult saying 'hey let me show you this" and start to show my head lice to him, without even bringing me in the conversation. Its like as a kid, I was not even existed.

I remember that incident hurt my esteem so badly that I was scared of getting a hair cut, in the school I started wearing a cap on full time basis so no one can see my head or notice any lice, I was sacred of sitting on the front bench and started sitting on the last row, so no one is sitting behind me and can look at my head/hair
