HAVE YOU EVER BEEN SLAPPED BY GOD?

I'm not sure how to start this.
I'm not proud of it. Maybe you will judge me to be a bad person, an ungrateful person. And you may be right.
Sometimes when I am tired, because a little boy didn't take a nap or he acts up in a restaurant or I have to clean up throw up, or the little boy refuses to be potty trained, or finds the pencil that I couldn't find for an hour, and writes on the wall...or any number of things, I feel resentment creep in. I should be able to do anything I want at this point in my life. Work, go away for the weekend, go to dinner in peace. NOT clean walls.
Now to go back in time a little.
I had my 2 oldest very early in life. A military dr. did not follow any medical protocol when I had my gallbladder out at age 22, and said hey, you want me to tie your tubes while I'm in there? (I had told him I was done having children) I was 22 with 2 kids, and not enough common sense to look more than 10 minutes into the future. He tied my tubes at age 22, I was divorced 3 months later.
A couple years later along comes the most amazing man in the world. He was 36, never married. He knew I could not have anymore children when we married, he was fine with that. I was not. In my mind he deserved a baby "of his own". We tried to have the surgery reversed, but there was too much damage. NO babies.
We had the opportunity to adopt a 5 month old a few months after we were married and done it.(she's 19 now!)
But in the back of my mind he deserved a son, a son I could not give him.
I prayed God would allow me to give him a son. Crazy I know. I saw the surgery report, no eggs were coming out of those tubes.EVER. I prayed that prayer til I was about 40. By then I knew it was too late and too crazy. And who says He didn't answer my prayers all those years ago with our daughter? Plus our 2 older daughters who love him as tho he was their father.
Back to the resentment.....
At times it has got the best of me. Don't get me wrong I love that boy with all my heart. But God had to show me something and He had to make sure I saw it.
Today while watching a UTube video, of all things. God smacked me.
He said I heard your prayers. YOU messed up my plans for your life, by having the surgery. I did give you a son. I answered your prayers, not on your terms, but Mine. I gave you the son you prayed for.
The boy was born right before my 40th birthday. It was a miracle he came to us. Healthy, infant males are nearly impossible to get from foster care. Especially when your not looking for them.
If I would have become pregnant at 40 would I have resented it? I did pray for it after all. So why do I resent not being able to do the things I could do without a 2 yr old?
God gave me the desires of my heart, I will resent it no more. Sometimes I am a blind fool.
