Everyone is right, you are talented, but as long as you don't believe it, and judge your worth based upon your perceived opinion's of others, you're trapped. Do you honestly believe they are a better judge of your value than you? If you could read their minds, you wouldn't have so much reverence for them. Einstein said the same thing about himself.
You're the one who has trapped yourself, so until you are truly ready to break your self-imposed bonds, you will re-live the same old fears.
