Lately I've been feeling really "depressed" and I can't figure out why, it's like I feel like I'm not doing a good enough job as a mother and my son deserves so much more even though I'm trying so damn hard to be enough. I find myself just crying for no reason at nights feeling so out of sorts. I try not to cry in front of my little one but when I do he just puts his hands on my face and it makes my heart melt. Motherhood is tough 😞
