can i ever catch a break

im on lexapro for my ocd and depression but i feel like my premenstrual exacerbation is getting in the way of it working to the fullest extent. im currently on 30 mg of lexapro and i’ve noticed it helping with my depression, removing a noticeable amount of my emotional sensitivity and general overwhelming sadness. i hardly feel the urge to cry anymore which is rlly helpful because like i said, i can sometimes be too emotional for my liking. but today im 13 days away from my before and just before i had my ovulation week, and it made me feel awful. i am tired and unmotivated and my ocd feels worse. i feel little joy and cant stop binge eating esp bc its almost the only thing that makes me feel anything. i can feel it in my body that my menstrual cycle is wearing me down and i dont think lexapro is gonna cut it. i started with 5 mg then 10 mg then 20 mg and it didnt do much for my depression. i wanna get better but i dont know what to do.
