First, that others have pain doesn't in any way change the pain you feel. Hurting is hurting, period. Nobody should be put in a situation where they are hurt like that, period. A really wise friend once told me that it's dumb to compare sufferings. Suffering is suffering, and it doesn't matter if it is better or worse than someone else's. No need to apologize here. If you were in the hospital, in pain, it wouldn't be wrong to take pain medication - even if someone else there was injured too.
Second, based on your avatar, you look great and have a feminine elegance in the way you carry yourself.
Third, you have the human right to "be".
Finally, it is so sad that people would try to take away someone's joy and peace. I'm sad that you had to deal with that garbage. It's sad that they would try to intimidate you and terrorize you - when you're just being yourself, being honest with the world. And it's not just low IQ (although I'm sure that these were no geniuses) - it's much worse in people that causes this. I've known plenty of people with low IQs who were decent, kind people - these creeps had a much deeper problem than just their low intelligence. They have low humanity.
