noexcuse,
Raising children IS exhausting - mentally, emotionally, and physically. I found that to be the case when mine were young and this was before I developed my unhealthy relationship with alcohol.
Rehab sounds like a fine idea - can you make that work?
If the only reason not go is that it's "the easy way," by all means take it easy!
You know it's not the end-all cure, but it will give you a running start to what comes next, right?
No one deserves to feel how you do right now.
