Your experience in school sounds exactly like mine when it started for me in about 4th grade when I first had to get glasses. I'm sorry and unfortunately know all too well how much pain you have and how you feel you need to build this wall to protect yourself.

My advice my friend is to try to get some help from somewhere, either a school counselor or tell your parents you would like to speak to someone and let them know it's not just a phase you'll grow out of. This is all too fragile a time to be subjected to these feelings. I wish I knew then what I know now and had gotten some help from somewhere. I was an only child so I didn't even have a sibling to discuss it with.

I hope you find a way to deal with this as the anger could get even worse and then it either gets turned on yourself or against others, neither of which is a good thing to have. The anger, channeled in the right direction, can be a force for the good (it studying harder to achieve great things) but it can a dangerous double-edged sword when it rears it's ugly head at the wrong person at the wrong time.

If you need/want to talk more please feel free to PM me. You'll find many MANY wonderful people here on this board who are so kind and giving even though so many of us are suffering and wrestling with out own demons.

Be well and love yourself...
