Those seem pretty normal. Zoloft is an SSRI, used to treat depression. It also has uses in many anxiety disorders, such as OCD.

Seroquel is a mood stabilizer and is used in the treatment of bipolar disorder. I believe it is also used as an augment to a partially (but not completely) effective SSRI for depression.

Abilify is similar to Seroquel, a mood stabilizer also used as an add-on to SSRI treatment.

All in all, that doesn't sound too extreme or unusual. If you are having side effect issues or other concerns, it would be beneficial to talk to your pdoc.
