What can i do about poor cognitive abilities?

I looked on the web for the word cognitive.You say you've seen doctors concerning this matter and you don't feel like they;ve helped.I've been told that it is not good to push religion on people,but I must say believing in Jesus and embracing my faith,reading the bible,helped me out many times in my life.Next like myself you need to work on your self esteem.Don't be so hard on yourself.All humans make mistakes,whether anyone notices or not.If you don't know something,don't be afraid to ask questions.Hold your head up high,smile,and just know that no other mortal on this earth is any better than you.Last but not least don;t start anything you can't finnish,and finnish things you start one at a time.Good luck.
