Sad during pregnancy

Tasha β€’ Married to my high school sweetheart πŸ’– With two beautiful babies! πŸ’–πŸ’™ Pregnant w/ #3 πŸ₯°
So lately I get really upset, Idk why. I have depression, and it can get really bad, but sometimes I get so upset over things that it lasts for like hours. I want it to stop because I feel like it's gonna make this pregnancy hell :(
