Decision making symptoms and conditions

I am 24 and used the NuvaRing for almost 3 years. As I finished up college at 21 and directly afterwards I was becoming more and more depressed, which I first attributed to the transition. It was while I was still in college that I also noticed a change in my ability to concentrate and remember. Focus and decision-making were abnormally difficult. My moodiness and depression increased over the next two years, my sensitivity to other's comments became more acute and I constantly felt at the edge of tears. I had little to no enthusiasm for even my favorite activities, no energy for sports/physical exercise, and no interest in sex with my partner. I required more sleep, always feeling tired when I woke up. I also began to have headaches, which had never been a trouble before.
I have been off the NuvaRing for about 3 weeks. Like some have posted earlier, I feel like a dark cloud has lifted and I can enjoy life again. Notable changes over the last couple of weeks have included:

1. Waking up naturally in the morning, almost 2 hrs earlier than before
2. Dramatic increase in ability to focus and remember (effectively study)
3. Happy mood and few to no self-deprecating thoughts
4. Increased energy
5. Enjoyment of flavors
6. General clarity of thought
7. Return of interest/enthusiasm, competitive spirit
8. Interest in sex
9. Decrease in headaches

I am absolutely thrilled to have identified the NuvaRing as the source of these issues and having eliminated it from my routine. I feel like I have my life back.

I've noticed that when I lay down my arms and legs and stomach jerk. Sometimes the movement is so strong that it wakes me up. One time I woke up thinking I was falling. Also, horrible memory loss. One day I was home cleaning my house and I forgot to pick my 8 year old son up from school. Also experience fatigue. My gynecologist has prescribed 300mg Wellbutrin and 80mg of Prozac for my depression and PMS syndrome. I'm concerned because everyone is telling me I should be monitored while being of this medication. Also, I question my decision making. Another thing is I was always scared of rollercoasters -- well, on this medicine I can easily sit in the first seat of a rollercoaster ride and go on it 4 times without being scared.
That also makes me nervous. Headaches, sleeplessness, dizziness and lights are too bright.
