anxiety and stress
"I have been on Zoloft (sertraline) for a little over a year. It has made a huge difference in my quality of life - I no longer have constant anxiety or am paralyzed by inability to make a decision. I was afraid that it would make me feel like a zombie or feel emotionless, but instead I just feel much more in control and able to move on from things like a normal person. 
I was worried about weight gain on this, but my doc combined it with Wellbutrin to help with my depression and offset the Zoloft side effects, and it turned out to be a perfect combo!"
