Depo-Provera Contraceptive and crazy job

Horrible!! Awful!!! I've only take the second shot and just recently learned that it's been ruining my life. No one told me about its side effects. I had to find out on my own after months of thinking I was going crazy. Job performance plummeted, heartbreaking problems with my otherwise wonderful love life, loss of friends and desire to even communicate with anyone. Severe depression (including suicidal thoughts), horrible moods swings, loss of hair, headaches, constant bleeding, and worst of all this feeling of doom that horrible things are going to happen to me. I wish I had been forewarned. I was just told that the shot was a great contraceptive. Now I feel like I can't trust anyone.
