Just a new wife needing help!

I love my husband, I love my relationship, and I love married life. But I am incredibly mentally tired all the time. Being 20 and one of the first people in my friends to be married and have a house. I feel completely alone and turning to my old fashioned mom and mother in law just adds so much more pressure. Especially from my mom who could do it all in my eyes with a high position, two kids, a home, and a husband, her home always looked like we were expecting someone and she always went out wanting to be the best dressed. So now me being married and having a home of my own I feel so disappointed in myself that I can’t keep up with the house work, dinner every night, laundry, groceries, bills, and somehow take care of myself. And lately with my man on call it just makes it worse I use to be able to handle being on my own but this week I seem so off my game lately my house is a mess, laundry is everywhere, and I have hardly seen my husband in the last two days. How can I think of babies when I can’t go a couple of months without having a breakdown? I want to be strong for my husband for my home for my own health. No one ever prepared me for all this pressure put on me by old fashioned ways!
