It is good you are becoming aware of your short-comings. Once you see your short-comings, you can easily change them. It is when they stay in our blind spot that we stay stuck in the behaviors.
 
Ask the Light to come show you what you cannot see. As the Light shines on this dark spot in your consciousness, you must be willing to really see what is there. You do not get the luxury of denial or innocence or just not knowing any more. If you ask, you shall receive.
 
Be ready with an open heart to receive the Light: be willing to see what it shows you; be strong enough to interpret it clearly; and be courageous enough to take action on what you have seen.
