This definately sounds like side effects to your meds, some doctors are inclined to believe that some patients take a while to "settle into" their medication but if it is making you so uncomfortable why not go for a second opinion or try a more natural and side effect free treatment.

No matter what the doctor says, he does not know exactly what you are feeling and the effect it is having on you mentally. You know what feels right for you and don't let anyone else tell you otherwise.
