I need guidence for a person with ADHA & Marriage

I need guidance for a person with ADHA & Marriage...

I think I have untreated undiagnosed ADHD.

My wife and myself are both stubborn and opinionated however I have these brief angry outbursts, short term memory loss and I get distracted very easy when in a conversation especially towards my wife when she questions or comments on something I've done wrong. I've been reading this blog and it sounds like I have adult ADHD.

I read and understand things and for a while things are great then it is as if I forget everything I've learned just a week ago. Its a constant struggle and I want to do something for myself but also for my wife as I totally love her.

I am a good husband most of the time but as my wife tells me the 20% of the time that I'm not erases all the good that I have done.

I'm not sure what to do or where to start, I guess admitting that I have a problem and need to do something about it is my first step.

Thanks
