Hmm... now my insomnia is back, in a big way

I realize now that it is clearly connected with stress from my job. Would this be an aggravation, at this late date, or a sign that further treatment is needed? I am still looking for yet another homeopath, but rather confused on what to do because my symptoms are so odd.
Don't know if this makes a difference, but I took Arnica 6C once last weekend for a bad bruise from sledding -- it did help quite a bit.
