ACOA and ADD

Thought my 8 yr old son had dyslexia until recently diagnosed with ADD.  I now know I have it and can recognize the family history.  In addition, I am an ACOA.  I feel double whammied and don't even know where to start.  I've been going to ACOA mtgs for six months and they are helping.  But I now clearly see many issues with my marriage.  Where do I start since there are many similarities between ACOA and Add?  Do I see a psychiatrist? Should I get a diagnoses first? Do I start stimulants?  Do I ask my husband to go to therapy?  (These last six months I think he is trying to support me but remains quiet and doesn't have much to say.)  i also recognize many ACOA and ADD traits in him but when i mention these to him i think he thinks i have really lost my mind.  We have just started our son on meds and it has been stressful for the both of us.  Lost and confused and I don't know where or how to begin dealing with these recent discoveries.
