You are not alone in this struggle. In my years I have many time wondered what is the reason for continuing this struggle.
I beleive one of our biggest mistakes is comparing ourselves and our accomplishments with those of others, or feeling a need to meet the expectations of others whose opinion we value.
Each life is individual and no two people experience life in the same way. What may come easy for you may present great difficulty for another. Like wise what is earier for others may be a struggle for you. Therefore comparison is not fruitful and will only lead to more of the same.
What you must try to remember is that what ever you are going through at any given moment is subject change and will be different in time.
To contemplate giving up is not the answer you are looking for. Great sadness is just the flip side of great joy and must be endured in order to experience either
As has been said that is like chosing a permanent solution to a temporary problem. In other words this too shall pass.
With the light comes understanding.
Don't forget to turn your problems over to whatever is your higher power. Trust that your God will supply all your needs.
