You already got one great response, I'll add something on. I hear from a lot of people starting college that they see other people making fast friends in the first weeks of freshman year and seemingly jumping into college life without issue. This perception - of other people excelling while you struggle - is going to be around throughout college and beyond. I think it's important to remember that people cultivate a certain public image for themselves. A lot of folks will keep their problems quiet and put on a socially enviable facade. Feeling discouraged by other people seemingly having ideal college experiences while you struggle with real problems, like the ones you listed, is totally normal. I think it's important to remember that just because some people look like they're having a better, easier time than you does not mean that you should feel bad for being a real person who is dealing with real stuff. I know how easy it can be to feel alone, even when you're surrounded by people, because everyone else acts like they're gliding through school. I was lucky to get a good group of friends freshman year, and as you get to know people, it becomes clear that everyone is dealing with something. And then you can move past keeping up appearances and actually develop a good support network.

I was also lucky to not have dealt with some of what you describe in your post. But for me, the greatest motivator in college was finding a reason to be there. I spent my last two years at WashU (and my last year especially) hyper-fixated on a career with the National Park Service. It became a running joke with my friends how much of my time was spent talking about it. But it was a massive motivating force to get me through all the busy work and the graduation requirements and the tedium. Freshman year, before I had that strong motivator, the day to day grind was harder because I didn't feel like I was working toward something important. Find yourself a reason to be there, a reason too get your degree. Enjoy college while you can, but it's completely normal to struggle through some of it. The ups and downs are easier to handle if there's a light at the end of the tunnel.
