So I'm in the process of getting my diagnosis, as of next Wednesday I will probably receive the diagnosis because I tick all the boxes for ADHD inattentive type formally known as ADD.

This didn't come easy, I talked to a friend of mine who lives with the same diagnosis and it was in fact a relationship in shambles that got him to seek help and I'm afraid I'm heading towards the same path. 
 

I have failed and messed up in so many different areas of our lives and relationship that I've caused a significant rift between us and enormous amounts of resentment in my wife. 
To list some of the things:

I have forgotten to pay bills throughout our relationship which has caused horrible credit ratings, having our electricity shut off, having bill collectors knocking on our door, having my salary garnished- all of this while having the funds to pay the bills but there's just this switch in my head that just kept on procrastinating and I hated myself for it. 
 

However I got a spurt of energy and excitement as I was getting the initial interviews for my diagnosis that I decided- let's get ALL OF IT taken care off! So I settled all my debts and bills, however, because I was so ashamed of having put myself in that situation in the first place I lied to my wife and said that I had saved the money. 
 

This was the last straw for my wife and she kicked me out, she did however, invite me back home but is still fuming. Which is understandable considering I've consistently been inconsistent and unreliable which has caused her a lot of pain, crushed hopes and dreams. She on the other hand has always been reliable and have been the one to do all of the mental lifting in the relationship, all the planning and hasn't ever missed a bill. 
 

Advising her to just let it go feels demanding, I understand that she harbors a lot of anger towards me, I caused it. I feel a lot of resentment towards myself not having seen the signs earlier, there's so many things both privately and professionally that could have been a lot smoother had I had the diagnosis. 
 

How do you move past the anger, resentment and pain? I did read the chapter but I would like to get additional resources especially from the perspective of the one who caused the pain what we can do to seek forgiveness. 
 

Also quick note: English isn't my first language so any grammar or other error is due to that fact.
