Looking for Advice on Buspar and Anxiety Medications

okay, so i currently take 4.5mg vraylar; 100mg pristiq; 40mg vyvanse; & my newest addition of 15mg buspirone twice a day. anyone going through anything similar? additionally, what are your thoughts on buspar? like i said, it's my newest med for persistent anxiety & im very unsure about it based on reviews & articles i've read. as far as treating anxiety, i've tried prozac, zoloft (both of which were to treat depression, but didn't help my anxiety at all - it worsened), hydroxyzine, propranolol, klonopin, & now buspar. i've taken the genesight test, and genetically, out of all SSRIs, SNRIs, etc., pristiq, fetzima, emsam & viibryd are the only ones that would have a positive effect on me, & i'm already taking pristiq, which is an SNRI. i haven't reacted well to many classes of anxiety medications & i’m gonna be so sad if buspar doesn't work out.
