Postpartum depression

I have postpartum depression pretty hard, it’s winter, -20 or -15 outside most the time in Canada. We live in a basement suite with little to no natural light which affects my mental health greatly, Ive asked my husband to help us find somewhere to move for over a year, he doesn’t care to look. Don’t have time to even brush my hair some days, my husband spends most his time on games or on his phone scrolling. Even if I ask him for some us time quote literally 40 times a day. I don’t even ask anymore don’t have the energy. I don’t have any support, my friends don’t care or have their own issues and I’m not close enough to talk to them anyway. I left my family in the past as they are all much too abusive to be around. And my dad passed when I was 13. So i have no family. My husband’s family isn’t a talking one and they mostly ignore my existence anyway which makes me feel like garbage. Idk I hate complaining, I feel so alone and so sad, I cry most days, we’ll actually everyday, don’t know what to do. I’m considering packing up my bags and my 6 month old daughters things and leaving just to get a week or two or something out in the sunlight or anything. Just a day outside somewhere or maybe a morning to get myself ready would be nice. I’m sick of feeling so alone. With not even one soul to talk to, I truly feel depressed and like life is completely hopeless.
