I feel this way often... But just continue to be you, every thing is temporary. Be confident in who you are on the inside and show that inner confidence outward, we were all made by Jehovah and he finds you beautiful. You're one of his master pieces (:
'You won't figure out who you really are by pleasing people..' ~ Don Miller / so only say yes to things when you really mean it, and say no when you don't. Don't fall into the trap of living for the praise of people, because often they're just as broken as we are, and words can be so cheap. So don't let people pleasing take away who you truly are - it certainly ain't the best for you!
