get up and better yourself and forget about the people that pushed you down... Just remember this saying "No matter how you feel, get up, dress up, show up, and NEVER give up" show everyone that doubts you that they are wrong.
The world is full of people who make you feel like you can't, you won't, you shouldn't. And sometimes it comes from the people closest to us. Be somebody's cheerleader. Encourage, lift, support. Be THAT.
