I know with an education in naturopathic healing i'm supposed to agree with meditation and breathing techniques and suggest other methods but frankly I don't think they'll help with what sounds like dependence.
My pharmacology background tells me pharma. I'd say try a tricyclic antidepressant like trazodone or nortriptyline every other night before bed or maybe even a long acting, low dose antipsychotic like (again, LOW DOSE) olanzapine or quetiapine. Any of the above will help with calming, sleep (i'm assuming that's a problem) and the mild depression you mentioned.
As always, just suggestions, not a sub for a dr and also aways be sure of no allergies to tricyclics before trying. The reactions are rare but severe when they do occur.
