I have a younger sister who is SUPERR attached to me. I love unconditionally but she just won't leave me alone at times. I always wanted a close friend but I feel so guilty that I don't feel that attachment towards her. I'm 18 and she's 10... I try my best to be her sister and bestfriend but sometimes I want to go places w/o her. What do I do? I always end up being annoyed with her and end up telling her something that hurts her.
