Hi Midlife,
Glad your here posting about your progress.
I remember my "brain in a blender" stage in early recovery...heck I still get episodes of it, but they are not as scary because I know they will pass.
Recovery doesn't happen overnight, like any big change it takes awhile for things to fall into place, and I know that I had a hard time being patient and keeping the faith.
Spending time reading and staying active on this forum has been a huge help to me. I borrowed hope and faith from the people here who had gone into recovery for me.
