My Only Mistake Was Not Letting You Down

I always can't let someone down whenever that person means something to me.. I'm always afraid of rejection.. always afraid that that person might get mad at me or disappointed that he/she will not talk to me anymore.. not knowing that if that person really likes me and will like me, no need for me to please him/her all the time. sometimes i just feel they don't even appreciate what I'm doing. :( I'm so stupid. I don't want to be bitter.. but these experiences makes me.. :/
