Vent post/depressed

Like I get where she’s coming from...but I still wanted to celebrate. She didn’t even let me explain anything before she jumped down my throat. I don’t know why she thinks I need her permission like what? It was rude. And I’ve always had issues with my mom. Now I don’t even want to do anything, my depression has been so bad this pregnancy. I JUST started to get excited at 20 weeks and she def shot that rite down. I wish someone understood. My fiancé knows I’ve been on medication since high school for my depression and anxiety but he just tells me to relax or that I have nothing to be upset about which doesn’t help. My mom always tries to one up me when I try talking to her like my issues aren’t valid enough and hers are worse. Idk, guess this excitement is gone again.
