How to get through weird transition into my 30s?

I’m (28F) not sure if anyone else can relate to this and offer some wisdom, but I’m finding myself feeling super lost as I head towards my 30s. I ended a 5 year relationship almost a year ago, and finished grad school and moved into a new career. So there’s been a lot of change as well, but I just find myself feeling so lost so much of the time. I’m finally making better money as I gradually work into my new career, I’m at least free of the tumultuous relationship, I have lots of good friends and fulfilling hobbies. But I can’t help just feeling “off” a lot and not sure what direction to move in. I date but am not having much luck, partially maybe because I still don’t exactly know who I am or what I want. But it seems like by 30 you’re kind of supposed to have some idea. Can anyone relate or give some advice here?
