I feel alone all the time, if someone tries to communicate, i can't speak and i just hope they go away from me and let me be like i was. i help people if i can but i don't get the same in return. i think something is bad within me that makes me stay away from others or they don't want to stay with me. i don't have even one true friend. when a teacher asks me questions, my mouth waters so quick that it makes me halt after 30 seconds, it is a big shame and i feel really insulted about it. HELP ME.
