Sounds like you're an over achiever who equates achieving and perfection with earning love and self worth. Maybe you had a very transactional childhood where good grades were rewarded with love and attention and bad behaviour meant being ignored?
Then you see your children's behaviour as a reflection on you rather than normal challenging behaviour.
You are working yourself into the ground and subconsciously expect praise / reward for doing so.
Rest and your needs feels selfish and 'bad' / scary that your subconscious feels you will be punished for / or not loved.
Everyone needs to feel loved. Your subconscious is replaying aspects of your childhood and using the skills you learnt very young to protect you and now those skills are hurting you, not protecting you.
Some good therapy with a highly trained psychologist might be very insightful and help you understand where these deep feelings come from that are ultimately burning you out and causing resentment.
It's not unusual to uncover unconscious rules that you have internalised. Having someone walk with you us you unpick everything can create lasting positive change. Do you have private health insurance with work? Strongly suggest accessing a Dr of phycology and having regular therapy thru private insurance.
You may leave your job or you may stay especially if you 'allow' yourself more help at home. Divert your resources to a part time nanny and do what fathers have always done and get yourself up for work and just go! Have paid support in the house to make your life easier and by default give your children a happier and calmer mother. Be the fun one at weekends! You may have to unclench (meant kindly, I'm exactly the same!) and learn how to play / stay in the moment with your small children. The one place I found I could play with my children was swimming...no phones and had to hold them a lot! I had to learn how to play with them too. I really really struggled with playing so in the end made it work (sometimes!) by doing things I could manage and having a set time (painting together with music on but only for an hour with snacks ready at the end)
You've identified this is not the way you want to live...only you can change your life. I think you would benefit from some internal investigation and take control of your own happiness...it's not for your children to give you, it even your husband. Good luck ❤️
