If you're hearing voices (and don't feel bad if you are, since this is a common symptom for many people who suffer from a mental illness) then you may need to investigate medications geared toward anti-psychotics and mood stabilizers. In addition to having anxiety issues, you maybe bipolar. Also note bipolar disease affects millions of people, which include public figures like Catherine Zeta Jones (who won Best Actress oscar in Chicago), and Jean Claude Van Damme (who is the famous martial arts actor from late eighties/ early nineties, while appearing in notable films such as Bloodsport). So you are not alone in having this this type of mental illness.
Buspar (buspirone) may not be the right med for you. It's mostly meant to manage mild anxiety. Zoloft, at higher dosages, can handle the anxiety which may feel like psychosis.
It's good you're taking medication, under the current supervision of a doctor, however I think you need to get your medications tweaked. Discuss all your symptoms with your doctor.
