Help!

i’ve been thrown different antidepressants/bipolar disorder medications throughout the course of around 6 months. i was put on an EXTREMELY high dosage of one medicine that really messed up my brain chemistry. ever since i’ve been on meds, i’ve found that i can’t get wet. it’s very dry down there, and no matter how sexually turned on i am, i just can’t seem to get lubrication. it’s very uncomfortable and often causes minor sexual injury, actually. any tips?
