If i had to guess based upon your information i would say your E2 is high and you test levels are low - coupled with the fact that your Clomid dose is unusually high.

Thats a cocktail for depression, if i ever saw one.

Im curious about your AI on your cycle. What was your protocol? And can you elaborate on previous use and AI? Is there anything that would indicate that you were NOT dosing enough AI on cycle? OR...perhaps too much? (but i doubt that)
