36 weeks first time mum

Im 19 years old with my first baby due on the 29th. Im soooooo anxious about labour im so scared. Also im starting to doubt myself...thinking that i cant even be a mum and im gunna struggle so much after hes born i just know im gunna be a wreck😭 my partner will be working 10hour shifts a day, so ill praticlly be doing everything on my own, i just don't have a good feeling about this.  i hate feeling like this but I can't help it. Any other mums felt like this before?
