Year11 soon to be leavers

I've just had a realisation that once GCSEs are over school is over, meaning no seeing friends, teachers, the normal routine. This is actually kinda worrying me more than sitting my actual GCSEs.I don't think that i would've actually ever said this but l like school (perhaps it's because i've forgotten all the bad things that have happened) i am going to miss all of the little things like lunch periods, normality and even just seeing people in the corridors even if they aren't in my class/year or teach me its just the normality of seeing them.I know it has to end some day but i don't want it to!
For some annoying reason I get very emotional and easily form attachments about these sort of things so have you got any coping strategies for leaving school and moving on/letting go? I'm trying to think of bad reasons that will make me want to leave like i guess the change of the new younger years coming and the lack of room we have in the canteen, the pressure constant revision and exams, the horrible seating plans, siting next to people who make me on edge bc of their intelligence and then expectations of me ... but i can't really think of more as i feel like college is going to be way worse than any of these seem.

Don’t worry, everything is going to be fine!
I’ve felt the same way in the same situation.
I’ve just moved schools after GCSEs and it’s definitely not a stable toll on my emotions on the first week. This is normal for many of those who struggle with attachments as you will definitely miss your old lifestyle.
Change is hard to accept and we will inevitable need to face it either way - nothing lasts forever.
On the brighter side, our links to the attachments we make are never snuffed out; There is always something or someone that will link you back to the past and remind you of all the happy memories you’ve made. Don’t let the hard feelings sway you to a negative mindset - try to find the glimmer that brings you joy in finding new opportunities.
Moreover, there will be tons of people in your college who are feeling the same way - you’re not alone!
I can tell you’re emotionally strong and can face this situation. If you feel like crying on the first week, go ahead - it’ll make you feel better in the long-run as you’d not be bottling up your emotions.
Be brave, wishing you all the best.

Thank you for the support!! It just feels like my school is family to me (probably because i spend half my day there) but it hurts to think that it's going to end and i will no longer be a part of my school for some reason all the bad things i thought of my school are just disappearing like even today i didn't have the best day but for some reason the fact i am leaving instantly over rides those feelings. And it's so hard to just state what i like about school because i don't actually even know, so that i can get over it. It just feels like a part of me is missing and i haven't even left yet, perhaps these changes from y10 to y11 is better because it will make the move less sad because i dont enjoy y11 as much. y11 just feels way more different than it use to be in y10 i really miss it and i know i can never go back but i really want to. It's hard to appreciate the moment when the future just hits you like a rock and my feelings is what's holding me down like an anchor. I need to become more positive but its just not me.

I get it, it’s definitely hard to enjoy the present when the future awaits for you in the midst.
That’s why you need to find something enjoyable to do in the present, make some memories! Although the moments don’t last, the memories remain forever.

Thank you for the advice!! I love that quote to live by 'Although the moments don’t last, the memories remain forever.' 🙂
