I don't know... Don't take this personally, but sometimes we have to suck it up and move on with life... Realise some people might just be playing with u and if they aren't ignore the ones that hurt u and love the ones that like u!
You are probably more sensitive to hurtful things than other people. This is also caused by hormones, especially in people undergoing puberty or adolescence. A doctor would be best placed to explain this to you.
I'm just like you. I just don't cry until I'm home :) . Try not to take things to heart, if it isn't a personal problem ("You have bad handwriting!"). If it IS personal ("Why are you so mean?"), then build off of it (in this case, try to be nicer). Such comments are rare, so it is a gift to know what people think of you, if you use the information. So basically, you have there options: 1. Ignore/forget the comment 2. Use the comment to build your life on 3. Cry ;( But once again, I'm like you- I cry, then choose another step of action.
You're a very sensitive person.. Words always hurt the most.. Just try to ignore those people. Just be happy with yourself and don't pay attention to them.. You will soon be able to ignore those negative comments. People are maybe only doing it because they know that you can be hurt easily and they just wanna do bad towards you.. Don't let them get to you anymore..
