Wife about done with me

Hey all,  I'm new here so go easy lol.  First of all, I know most of the problems in my marriage I brought on myself.  I have been diagnosed, and I do take meds.  I've made some mistakes I'm not ready to fully discuss.  For the last maybe year, my drinking has gotten worse (bad coping skill I know), and so has my ADHD.  My wife has slowly started withholding affection and intimacy from me.  She says she's "guarding" herself.  I have stopped drinking and plan on doing so for a few months at least.  Anyway,  things have gotten pretty bad lately and it's hard to communicate.  If I talk about my feelings, she gets mad.  She says she's trying to trust me again.  I get that.  It's just hard because it feels like I'm being punished, and the punishment doesn't fit the crime.  I think it is just going to take some time to get back to a good place with her.  And I get impatient.  I know that will be a difficult one bc you don't know all the details.  But I just wondered if anyone else out there might be going through something similar?
