Struggling with self care

I’m a stay at home mom to two little ones. I love it and although it’s exhausting at times I wouldn’t change it for the world. My husband is a great dad but is currently working a ton. He’s drained and stressed and I am on duty with the kids a lot of the time. My youngest is teething and in sleep regression and we all currently have a little cold. I’m so drained I feel like I have zero motivation. I know I’m neglecting myself but I feel like I don’t have a choice? I have to give up more sleep to get time to myself. We don’t have anyone reliable to watch the kids and I don’t trust strangers to watch them, we’re trying to save money, and I don’t have any friends. Lots of people in my life but no one I feel I can go to when I just need a friend. It’s HOT outside. I end up scrolling social media when I’m lonely and I honestly hate it. I call my mom sometimes just to have adult conversation but she talks SO much and ends up driving me crazy going on and on about random things going on in her life. How do you take care of yourself when it feels like you don’t have the time or energy to do it? I don’t even know what would help. I love my life I’m just drained.
