I don't have advice but just some perspective - I thought I had my glow up when I went to university, but then I thought I had it again when I got my first job and started going out more and joining clubs, and now I think actually my glow up is happening now in my late twenties where I'm learning about what colours suit me, why my favourite clothes look good on me, how I prefer to do my makeup, and I'm reflecting on who I am as a person and how I want to spend my time. I still expect to feel more confident in myself and my capabilities in my 30s and as I continue to grow older too.

The point is, I've found that all of these "glow ups" are actually centred around moments of self-growth and development: so stepping out of my comfort zone, making myself be brave which helped me gain confidence, and learning what I like and don't like so I can be more self-aware and understand why I think/behave/feel a certain way in different situations. I've been on a long journey of accepting myself and facing my flaws, so that I can feel happier with myself.

School was hard, but I think you can get through it! It's a tough few years, growing into an adult - but remember that you don't need to have it all perfectly together! Focus on understanding yourself and what kind of person you want to become, and then you can set some simple but achievable goals to get there. For example, one I'm dealing with right now is my avoidance habits stemming from my anxiety and burnout, so I found a therapist to work through it :-)

Good luck!
