zoloft has caused me to have an addictive personality

since I began taking zoloft about 5 years ago I have developed an addictive personality. Before starting zoloft I had great self-control and will-power.  Now I get addicted to everything I do:  drugs, shopping, sex, eating.  I tried to go off of zoloft about 2 years ago but I went into a deeper depression than I had ever been in before.  All I did was cry all the time.  In the shower, in the car, on the couch (which is where I usually remained)  I alternated between crying, wishing I were dead and yelling at my husband.  I am new to this site.  As I've been having a pretty bad battle with my depression the past couple of days I decided to go online and look for a support group.  Thanks for letting me share.  I'm interested in hearing other people's perspectives.
