Mid-20's Crisis?

So, it's that weird time where I'm graduating college and moving on to a big girl job, and it feels pretty lonely when everyone is branching out to different life paths and you're leaving a life of structure and getting thrown out into the street having to figure out your livelihood on your own. The rational part of me knows that everyone goes through this big change at some point, but when you're living it, you start to doubt yourself. Reflecting on how my identity came to be and all the nostalgia of early 2000-2010s social media and my literal childhood has blown up this "crisis" of confusion and fear of many big changes all happening so fast. I know I'll be fine but the certainty comes when you're on the other side looking back right?
