Really struggling at the moment

Have been really struggling with my depression lately, I’m a stay at home mum with my two boys (1yo & 3yo) but I’m really struggling with constantly feeling tired, the bout of housework I’m constantly trying to catch up on, the mum guilt because I feel like I’m trying to do so much housework that I’m not sitting down and playing with my kids enough, but at the same time when I’m sitting in the floor playing with them my back and hips are dying. my partners in a down mood struggling because he’s working 7 days a week but we still have nothing to show for it, plus struggling because “my dads around with me and the kids than he is” (we live with my parents for the moment) and when he’s in a mood it feels like he’s aiming it all at me. I don’t get any time for myself but when I try to make the time I feel constant guilt and I just don’t know how to get myself out of the black hole I’m feeling. My eldest is really pushing boundaries with not sharing, being very rude, talking back, slamming doors and I just feel like wer at each others throats all the time and we can’t even get out to go to the park or for a walk without a tantrum and it makes me not even want to try..
