Hi Mike,
You keep on telling yourself you have ADD then you will have it. Be positive!
I'm 70 and I suffer from AAADD (Age Activated Attention Deficit Disorder) (Joking) and I have the same problem. Lately I have been forcing myself to read.
You can play CD etc, but I would go to sleep.
Try reading your Bible first thing in the morning, by getting up a little bit earlier before going to work, or soon as you come home.
Everybody is different.
I am sorry be we must always remember that whatever words we speak over ourselves is what we will be.
Your disorder covers many aspects of life from physical, emotional, and spiritual. You are a Christian, and you are special to our Lord Jesus Christ, and your walk is spiritual. See if you can pull yourself over the hump that is in your path on your road to recovery, healing, success in your race of endurance.
Christian walk isn't easy, but when your faith soars, and you are able to overcome and conquer those hurdles that Satan put in your path, then nothing can stop you. Be blessed, in Jesus' Name.
