Quit army cadets stuck in unhappy situations what could i do (urgent)?

[Bella]

im 14
and about 5 months ago i quit cadets.I quit cadets as i found that it was getting boring and wasting my time also about 6 of my friends left ,But i regret it as i cant get extra qualifications and i have lost all of my friends they were like family to me we shared the best memories,They have got me through some very hard rough patches particularly this one guy. But its all over now i don't wanna join up again i don't enjoy it and all some of my old friends are gone . When i left i posted on there Facebook page i long speech saying how much i loved cadets and i wish them all the best in life and thank you for being there,i didn't get 1 reply they kicked me of the page.I told them i wished to stay in contact none of them did.Im very sad about this i only talk to this one person from cadets but even we dont speak that often.
How can i move on i cant just forget all of the memories?
Repeat i dont want to join up again

Why don't you just sign up again? You can still see your friends but do something for you and your future. Your friends can wait.
