Untreated ADHD leading my wife to want to run from marriage

Hello everyone I have been reading through these forums for about a month now trying to work up the nerve to make a post and ask for help or advice, but I'm at a breaking point in my marriage and really need to know what a community of people who have experience with ADHD to possibly sort threw some of this mess.

me and my wife have only been married for a year and a half, just had a baby girl a few months after marriage, I knew I had a problem with ADHD, but no money or insurance to go and get help. Long story short I have always had a short temper, just way to much going on in my head at any given time, and would react with the first thought or feeling I could get out. My wife constantly misunderstands what I am trying to say and takes it as a personal attack, and is now claiming that I was emotionally abusive and is in fear for our daughters safety. my therapist believes that because she has a previously diagnosed mood and anxiety disorder, she may be going threw a postpartum depression. I have been taking adderall for about a month now and my anger issues are under complete control. And I can think a lot more clearly then I have my entire life. I don't want to lose my wife, or my family any advice would be great, and I'm still working on getting thoughts out of my head clearly so any questions feel free to ask and I'll do my best to answer. Thank you for your time.
