If you do nothing but emote to her, she is going to see you as weak, just another b!tch. Women say they want that but they do NOT.. Be strong, confident, suffer in silence. Post it on a website, or complain to your male friends, but do NOT let her see you as some sniveling weakling.
If you must say something, show up with a plan. "Ive been very frustrated with my career/body/relationship with family. It's unfulfilling/bad boss/ whatever... but this is my plan to address that... "
