Teething baby-HELP!

My 4.5 month old has started teething . I literally feel like I’ve gone back in time to the newborn stage of getting up at all hours of the night and being sleep deprived . My depression has also returned, full force. I work a full time job with a long commute so it’s been a struggle getting through each day. He has teething toys, etc. any advice on how to get through the teething stage , because he doesn’t want to sleep.
