Please tell me it gets better

I have a scheduled c section November 2nd I’ve been fine throughout the whole pregnancy my son is so low my back always hurts I just started school back up Monday and this morning as I was walking downstairs to take my toddler to school I fell down about 6 stairs. I’m completely over everything right now and just feel soooo damn emotional I wanna give up I’m over being pregnant! Will this go away or will I feel like this for the next 2 months any advice helps
