Have you taken an ADD quiz before? ADD can be tough to spot in women. Some of your symptoms sound related to inconsistent dopamine levels, like ADDer's have.

Outside factors can play a role in symptoms getting worse, for instance, last fall I was very busy at work, taken on band chaperone duties which took over all my spare time, I was averaging 4-5 hours of sleep during the week and not much more on weekends. This lasted for about 4 months and was combined with major stress between me and my wife. My ADD symptoms were worse than they had been in years, in spite of still taking my meds.

Sorry for the ramble, but I thought it was worth mentioning.
