How are adults doing this?

I’m a twenty four year old woman, I’m planning on moving out with my boyfriend very soon, and I’m anxious about the future. I cook occasionally but rely heavily on takeout and freezer food. I wash my clothes only when I have literally ran out of things to wear, and only iron when it’s really bad. I work 9-5, and even then I struggle to get through a full work day. Even at the weekend, Saturday is for living life and Sunday feels like pre-work prep. How is everyone doing this? I feel like my life is either sleeping or working. Is everyone else just okay with this? What mindset am I lacking?
