what should i do

i got diagnosed at my school clinic but everyone was so judgmental and rude i haven’t gone but. however, i have run out of refills for my medication. i already feel so ashamed and going there is going to make me feel so much worse. i still haven’t told anyone, i’m disgusted with myself. what should i do? endure the embarrassment and shame the clinic puts on me? or wait until i’m really desperate?
