So depressed...

I have ADHD, diagnosed for over 10 years.  I take medication - I also have lupus.  These two things combined along with my general inability to fix anything are destroying my marriage. My husband is tired of me - and rightfully so.  We are living apart for the 2nd time, after being married 5 years.  We have 6 children between us, but none together.  I can't get it together.  He is tired of waiting for me to change.  Tired of my lack of follow through.  Tired.  I'm not suicidal, but I'm pretty damn close.  I don't want to live this chaotic life, but I don't know how to fix it.  We don't have the money for a coach, and our insurance doesn't cover it.  I feel like I'm drowning and I don't know how to swim.  I'm a smart woman - full scholarship to law school and great hyperfocus at times.  But I don't know how to be a wife, at least now the way my husband wants and deserves.  All I do is disappoint him (and myself).  

I wish I was "normal", or at least understood normal, whatever that is.  I didn't even know I could feel this sad.  I'm not even sure why I'm posting, except that I can't just keep crying.  Maybe it is time to just get divorced and be alone.  I don't know anymore.
