I'm currently nearly 30, for context. At 16 I was shy, but had a good group of friends and was well-liked amongst my peers. For some reason at 16 I decided I wanted a fresh start and to go to college rather than stay on at sixth form like nearly all of my classmates. All the adults in life say it would be the best thing for me, I'd grow in confidence and make lots of new friends. I went to college and it was awful. I didn't click with anyone, there were lots of mature students who had children or degrees and were retraining. I was a very young, naive 16 year old and couldn't form any friendships. I spent 2 years being so, so lonely. I'd spend lunch times hiding in the toilets or on the phone to my older sister in tears. I'd pray that I would fail my a-level exams so I had an excuse to drop out. It really impacted my self-esteem as it was the first time in my life having no friends. It led me to feel like nobody would ever want to be friends with me and I was destined to be a loner - and that became a self-fulfilling prophecy as at university and most jobs I've not made any friends.
In the meantime, everyone who stayed on at sixth form seemed to grow closer and form a big, close-knit friendship group. Fast forward to now and many of them have married or got engaged to each other within this group, there's now baby showers and bridal showers and housewarming parties. I feel so stunted compared to them. I have no friends, never been in a relationship. It felt like we were all on the same path until that decision to go to college. I've had so many years to make up for it and try catch up with them, but I just can't. I know I can't really blame it all on college, but it seemed like that was the start of things going down hill.
