SAHM having to go to work

I’ve been a SAHM since my daughter was born but my husband decided to go back to school full time so he could get a better job and we decided we would reverse rolls until he finishes(should take about 6 months give or take) and gets a good job. Well I finally got hired somewhere and my first day is Wednesday, but I’m having extreme anxiety about not only starting my first job ever but leaving my baby girl at home. I’m literally so sad I won’t be able to hangout with her all day and play with her and love on her. I’m so socially awkward and have extreme anxiety so of course I’m freaking out about having my first job
