fear of being forgotten

i'm afraid that one day everyone will forget about me. i know it's illogical but i'm scared that one day my friends will hate me or not remember who i am at all. i'm afraid that after i graduate no one will know who i am and i'll be all alone. i'm afraid when i die no one will remember i ever existed in the first place. i'm afraid people will forget our relationships even if they're small and in the end i mean nothing to them. i'm afraid that i just exist in other peoples mind rather than being apart of their life. i'm afraid that when my friends think of who their friends are, i may not be one of them. i'm afraid that while i mean nothing to people right now, the day i die (which isn't something i'm planning i'm talking when i'm old) no one will remember me or bother to show up to my funeral. i'm afraid everyone will forget my birthday. or what they mean to me. and that i just mean nothing to everyone. i'm afraid of being so insignificant no one ever realizes i was there to begin with.
