Just got fired. What next?

I just got let go from my FP&A analyst job. I was exactly 4 months into the role and was told the work that I was doing wasn’t where it needed to be and that they were going to hire a more senior experienced person to fill the position. There was no formal training, I learned the majority of the job on my own after not having any prior FP&A internship experience. My manager acknowledged my improvement and yet still let me go.

So, with that being said, what in the world do I do next? Does anyone have any general advice? Not looking for an answer of what my life should look like, but would love a sense of direction.
