Hi Borderlineann,
Welcome to PC
I personally have a high sex drive and the SSRI im on at the moment has suppressed my libido significantly which of course im not happy about so i know how you feel

Have you talked to your partner about your issues? Sometimes just increasing the intimacy without actually having sex might help you stay close and even improve your desire to have sex. If the problem continues you might want to go to your doc about it and see what he says. Good luck.
