dont cry too much if your childhood friend forgot you, you protected them and helped them through a lot so its not your fault if they desided to change croud.
dont blame yourself if bullysm is seen as cool between your classmates. you can always find someone else to have friendship with, maybe outside school, just open up more and dont lose hope on people. therere people you know little of that still remember you for little things youve done because you got out from the corner and made a positive impact on them, may it be a drawing or some help on homework or a joke you found embarassing or that comic that was your cry for help that worked.
so stay strong and stubborn, talk and dont let the pressure destroy you, or stress and anxiety are gonna bend you in a really bad way. thats really a part of me that i want back, so dont lose it.
(also for the love of god dont let your parents throw away our beloved comics, i cant find them anymore-)
ps: say always hi and smile to anyone, you never know if it will be the last time you get the chance.
