Give it time. I've gone through several growth and downsizing periods. Each time the people change and, therefore, the culture. Afterwards, everyone is kinda feeling out everyone else, both professionally and personally. The culture usually comes back, in my experience, but with different twists and personalities. Worst-case scenario, the job starts to feel like one, the joy gets less and less, and you end up looking for another one (of really any size) that had a culture that fits your personality. You're taking a healthy approach to this already, so let it play out before you back out. Good luck!
