"i am beginning my fourth week on 20mg fluoxetine taken each morning. i am recovering from a long term abusive relationship with a narcissist. i have a head injury that predisposes me to fatigue.  i asked the doctor to help me with my energy levels. i did not admit it but the underlying feeling i had was that &#039;everything was too much&#039; and &#039;nothing matters anyway&#039;. but nobody would have guessed how hopeless i had become. and had been for at least 10 years. initially i experienced all of the symptoms people warn about in the first few weeks. insomnia and occassional extreme anxiety were the worst. now i feel enthused about taking things one at a time and am enjoying the process. i have begun to sleep normally again. so far, so good."
