Emotions

I have a 3 year old son. I'm 9 weeks today with my second.. but it's been so hard to keep myself going. I'm always tired. Sick. And feeling a depression. Probably doesn't help with it being winter and cold. But I do make time for activities. But somedays... I don't wanna do anything or I feel like I'm in a hole. Idk how to feel better or get myself going. I did a bunch yesterday but have more chores and normal life things to do today, but I'm in such a slump. I'm just not sure it's normal or why I'm so down these days. I wanted this. I wanted to be happy. Hate that I'm feeling so down and out. I just wanna be normal and do normal life things without it feeling like I have to fight myself. 🤦🏻‍♀️
