Like what others said, it's really what you make of it. Take care of your health and push yourself to do things out of your routine, try new things or go to events even if you don't have anyone to go with. Be smart with your spending so you can afford experiences that matter to you (don't waste it all on eating out and coffee everyday)
I see lots of adults getting depressed because they just work, watch tv and order takeout.
There's gonna be tough times, I'm not someone with many friends but I still go alone to concerts, movies, the bar, vacations and worked on really feeling comfortable on my own which I think is important! & I've made friends along the way!!
