I just want a clear decision!!!

So I am halfway through my LDR orientation and I am thinking I might hate it. I like my coworkers and the doctors but I think I just don't like the job. I am thinking about returning to postpartum which i previously did for 5 years. My preceptor assures me I am picking up on things very quickly and she is very positive about me, but what I can't determine is whether or not I will ever enjoy it. I was perfectly happy with my PP job but felt I should try something new while still wanting to remain in OB.
I feel like i dread going to work. At first I brushed the feeling off as I was just not familiar with the unit/skills, but now that I am functioning more independently and still feel the same way.
Once I finally admitted to myself that I wanted to possibly go back to postpartum it felt like 10 tons off my chest.
Any advice on either returning to PP or how to get myself to like LDR???
