Carefree sounds like code for "parents did everything for me".

Most of what you say is part of growing up / new changes, not necessarily getting married. If you'd moved overseas for work you'd face the same thing (costs, routines, planning), except for space. And for space, that's just normal issues of balancing expectations and communicating with your husband. Jumping to "I guess we're just incompatible / I shouldn't do marriage" within 1 year is not a great mindset to have. Marriage is literally how you make it. Some couples spend a lot of time together, others don't. Go create whatever marriage you want with due compromise with your husband.

wait looking through your post history I don't understand you. You say here you're first year married and never stay over before marriage, but your history says husband looks after the kids plural, and you have a helper?

Anw if your life with a helper is still insufficiently carefree idk what to say.
