I don't know how to resolve this. And I really have to.
This ^^^^^^ will happen with time, trust me. Me and my wife had some real problems last year. My wife thought I should have everything fixed around day 50. Most of the time she couldn't understand why I still was having difficulty. It took continued work (what you must do) to keep my emotions in check.
To be honest, it took about 150 days to began getting more in sink (for lack of better words) with my emotions.
The answer here is TIME my friend. You will actually be surprised at how you deal with situations in the future. Your still healing.
Now I look back and see one screwed up individual last year. I can't believe how bad the poison had me screwed up. If you've read the facts on this addiction and what it's done to our brains it's a wonder we're able to heal. Think about it, the poison actually made our brains create extra hardware to combat our addiction. Our brains actually began believing it needed the poison to survive. Your addiction was in control of everything without you even realizing it. Now your taking that control back which isn't done overnight.
I recommend your girl reads these replies you've received. She needs a good understanding of what your going through. Maybe she can read this one sentence from me.
Monster will not be like this forever. I give you my word. You will like the new Monster. He will be more in control of his emotions than he's been in a long time. He will be more sure of himself. He will handle what life throws his way with more confidence and rational.
The new monster is a work in progress. One day at a time brother. Quit on.
