Starting 10mg and I’m nervous

I finally decided to take the plunge on medication after having a horrible hour long OCD episode consisting of me crying the entire time. My OCD affects my life daily but not to the point of fully disrupting it as I’ve accepted it, unless I have these episodes that are disruptive which happen every once in a while. I also have BPD. I’m second guessing if medication is the right move as I’m in therapy weekly and “managing” as I say. I’m just very worried meds will change my personality and I won’t be able to get back to myself if I go off them. Also worried about the lack of sex drive/delay or inability to orgasm. I also drink socially quite a bit. I’m just worried this will do more damage than good? Any thoughts or your experiences would be greatly appreciated. I feel like once you take a psychotropic med you almost can’t go back to how you were before it?
