Is anyone else an ‘old soul’ and have these problems?/ feel this way

I’m 18 and I’m exactly the same way! Even to the point where I have meaningful conversations with a teacher.
I’ve never found anyone else who is like this and my peers think it’s odd and teachers always seem to think there’s something upsetting me. But actually I just enjoy my own company and am perfectly content in my own world!
Here’s to loners by choice! 🥂

This made me so happy and same here!❤️

I don’t need the approval of others and I always get told I’m quiet, but I don’t think that’s a bad thing and I’m quite comfortable being that way I think it’s nice to observe and anticipate other people’s emotions.

This post sounds like you are seeking the approval of others and you're clearly seeking other similar people so maybe deep down you don't want to be a loner? You might just be in denial and using your 'old soul' as an excuse to not make the effort with people. Being an introvert is fine but sound like you think you're super woke, more mature than your peers and really unique. I don't think this is a choice, I think you're just still too young and scared to put yourself out there and this seems the easier option. It sounds like you're not giving people your age a chance and you're judging them too quickly. A lot of people share your interests but you just assume you're unique. Perhaps you won't meet anyone you really click with til you're at uni or in a job. But I think you'll regret closing yourself off so much. I probably sound a bit harsh but as an introvert who has also had friends who have done what you've done and got themselves in a depressed state, I'd quite like to prevent you from reaching that point. Luckily most of my friends who have been down that path haven now come out the other end and are letting people into their lives again.
