Exclusively pumping support??

Cara • Baby boy due May 30th, 2017!
My baby wont latch to my breast at all. Its been a rough 2 weeks, and my heart is broken that I can't breast feed him. Ive still been pumping and would like to continue. But its absolutely exhausting. How do you ladies who exclusively pump do this?? Its just so much extra work, I feel like just giving up :( I still try to latch him often because I dont want to give up on breast feeding but he screams. Its been really difficult for us, and I feel like I'm getting depressed. How do you get through this?? Any tips to make it easier?? Can someone share their positive experience with pumping?? Please help
