I'm hoping the Strattera helps out, although I fear the (initial) side effects.
See how it goes. If it doesn't help then I think you should get a second opinion/reevaluation of your med regime. IMHO, it is better to find an antidepressant that works well than to keep adding more and more meds to overcome the limitations of the one you're on. Polypharmacy is sometimes necessary, but it should be the last option when the simple ones have been exhausted.
