The anti-psychotics are used for excessive agitation and irritability. Sometimes, psycho-stimulants (ritalin, adderall) are used depending on your diagnosis. Are you taking anti-anxiety meds (klonopin, xanax, ativan, etc.) ? They can help to a degree. I have the same problem with constant irritability. It really messes with your mind, scatters your thoughts and screws up mental and physical energy.
