Don't obsess over your faults, or you will never enjoy the life that Jesus died to give you. Only God can change you, so talk to Him about your desires. The word says that those who wait on the Lord will change.
Meanwhile, quit taking your flaws so seriously. Don't let discouragement or depression rob you of your energy and make you angry. If you do, you may take that anger out on other people and miss the blessings God has in store for you today. Enjoy yourself, and lighten up! Take the right steps today toward the change you want by asking God to help you all day long.
