Yeah I have had a similar experience to you. At sixth form I had a couple pals but I didn’t really see much of anyone outside of school. I’m just finishing my first year of uni and I made pals but no one who I speak to / go out with often. I think my time was made harder by covid, but I still made some mistakes. My advice is join a society/ sports team. Even if you’re bad at sport, even if you’ve never tried it before, just go for it. I didn’t do this and I suffered because of it, so my plan is join at the end of this year, ready for next year. If you do this, it’ll make your life so much easier. Also, do volunteer work for your uni, that should be a good way to make proper friends. It’s inevitable that you’re gonna meet people, but the wider you cast your net, the better chance you have of making real friends. Also, don’t put yourself down. I used to hate my physical appearance, but I got over it. Go to the gym, slap on some hair gel/clay, look online for fashion advice, buy some decent clothes (doesn’t have to be Moncler or Gucci) and chin up. Confidence is the most important thing. You just gotta get yourself out there. It’s hard, but sometimes in life you just gotta hold your nose and dive in the deep end. That doesn’t just go for uni, but your entire life.
