Cry?..

Have you feel the feeling of you want to cry for no reason and some simole things made you cry a lot haha i think its funny at first but some others told me its not simple so i just think if theirs something wrong with me.... when i was in grade 5 all of my classmates starts bullying me and stole everything to me and they always judge me so maybe i became sensitive cuz of all pain that i recieve from the past

What do you think is wrong with me?
