Fear of time passing

2025 is around the corner and I have this obsession about wasting my teenage years. all I can think about is how I only have an xyz amount of time left. I feel like I wouldn't feel this way if the last 5 years of my life wasn’t horrible, but what can I rlly do atp?? lol..

I'm rly looking forward to college next year and im gonna make the best of it despite this obsession in the back of my mind
