Ashamed of my body and falling into depression. Advice?

I can’t stop gaining weight during this pregnancy. I’m 25 weeks and up almost 45lbs. My doc doesn’t say a word and says I am perfectly healthy. My face got super fat. I can’t stand seeing how big my hips are getting. Nothing fits at all anymore even some of my maternity clothes don’t fit right. I’m 6’ which doesn’t help bc normal clothes never fit my body anyways. I’m getting depressed and upset to the point where I want to go to work and come home and hide. I don’t know what to do anymore.
