Gosh, hearing of this type of thing always saddens me. The thought of some cruel, unkind, hurtful ''people'' making someone feel so much sadness is so incomprehensible

Please know you are very different from them. Their deliberate intention to make you feel this way shows you are far more kind and compassionate than them. Those monsters who said these harsh things to you are not worth your thoughts. Who cares if someone is not intelligent?? Being rude is far worse than lacking intelligence.
Forget the bullies. Always try your hardest to forget the bullies. Ignore them, always. I want you to have a wonderful evening, you deserve it after all this!!!! Treat yourself to something you enjoy!!
I really, really, really wish you well, mountainstream. You have a beautiful username
