good or bad ?

Its crazy, i've been on prozac for over a month now and it makes me feel numb. Like my thoughts don't run threw my head like they use to but my body still cries. Its starting to happen more and more i will start crying but when i try to think of whats wrong i get nothing but a weird feeling because this medication has blocked my thoughts .. I don't know if this is a good thing or a bad thing ? :(
