I am familiar with a lot of what you seem to be experiencing. I was not diagnosed with ADD until I was 43 years old. I got to a point in my life where I had a bunch of things hit me all at once and I became so over-whelmed and began to have anxiety attacks which finally sent me to my GP. The doc had me take a couple of the quick psych tests and he said I scored a little high on the BP quiz. My GP recommended a psych who quickly told me I was not BP, but ADD. I was surprised by the DX, although I used to always joke about being ADD because of my terrible short term memory, forgetfulness, procrastination and so on. My GP had put me on anti-depressants which helped a little at first, but really made me feel flat, not sad, not happy, just blah... I knew I had ADD after I read the first book (I read it in a weekend) It was the first book I had read all the way through in 10 years... The Adderall was a home run for me. I slept better, better mood, better concentration, my obsession with food ended, impulsive behaviors improved, time management improved, I was much better at work, home, everywhere...
Talk to your T about what you suspect and see what he/she thinks. Read "You Mean I'm Not Lazy, Stupid or Crazy" or "Delivered From Distraction". I read the first book with a highlighter, because so many things seemed to be right out of my head. Ask your T is they are knowledgable about ADD, because it is MUCH harder to DX in girls. One of the classic ADD (Non-Hyper) profiles is a girls who was always a straight "A" student, but had to work so hard, stay up late, but Driven to do so. (My sister was this way) Of course your psychiatrist will have to DX you. Many ADD symptoms are similar with other disorders, like BP. Other disorders can be present, comorbid with ADD, like anxiety, depression, ODD, OCD and others.
JDA... I hope you get some answers soon
