YES! It sounds like your hormones are out of whack, specifically your thyroid, progesterone, and testosterone (yes, women need this too). Thyroid: hair loss and fatigue Progesterone: depression and difficulty sleeping Testosterone: sex drive (as well as other things). This is textbook.
Go to a specialist in bio-identical hormone replacement because the last thing you want right now is to be on prescription drugs (which mask symptoms and don't alleviate the issue).
Or, e-mail me and I will help direct you.
Honestly, this should/could be an easy fix for you.
