Yes, that was my daughter... exactly. The first 6 or 7 years of her life took about 20 off of mine!
Her grade 2 teacher saved my sanity by telling me that my daughter was "highly atypical, extremely complex, and had the best adult manipulation skills I've ever witnessed." This from a teacher with 10+ years experience, so at least 240 kids in her class, plus all the others in the school that she had contact with. This helped me IMMENSELY because I knew it wasn't my parenting... my daughter was just really really intense.
I wish I had some tips and advice... I can tell you, though, that my daughter has mellowed tremendously with age (she's 9 1/2 now). It gets better...
