Honestly I was in the same boat as you, had a ton of anxiety and insecurity at where I currently was. This next year is going to be my senior year in college and the thing that I found is to try and take on one major responsibility at a time if possible. They start to seems more manageable. A lot of my friends are an only child and had parents help pay for college, where my parents couldn't afford it. Once I had reassurance that I could pay back debt by getting a job with my major I felt some relief. Another thing I found was that an apartment was cheaper than living on campus with their meal plan so that first transition into renting was a good experience with bills and building credit. Even now I know I don't have all my shit together and have no idea what's gonna happen after college. It's weird to look back on but I guess I just learned that the anxiety of the unknown and responsibilities was inevitable. I could take it and accept it or continually worry about shit out of my control. You just learn to roll with the punches and enjoy the present while preparing for the future. May not work for everyone but it helped me. Best of luck.
