Im a 17 yr old girl and my older sister is 19 and i feel as though my sister is always overshadowing me. She gets on better with people than i do and people seem to like her when they meet her for the first time, she's had 1 kindof boyfriend who really liked her (but theyve split up now) and she's met someone else who really likes her too, (he said to her she was the most beautiful person he's ever met,or something along those lines) which no one has ever said to me or anything to even imply im not ugly. also to make things worse one of my guy mates (who i had a major crush on a while ago) but he didnt feel the same said to me today he thought my sister was really attractive, which made me feel even worse.
Can anyone give me any advice as to what i should do to stop things like these getting me down?
