my old best friend

I haven't known anything about you in almost a year I really hope you're doing okay I really hope you're happy I really hope your life is going good they ask if I miss you I say I don't, you were my best friend but a toxic one I miss you anyways I felt happy around you I felt safe with you I felt understood by you I didn't feel alone with you even when we were away why did you leave me? did I do anything wrong? I always tried to be a good friend I tried to be the best even if I wasn't I hope you found better friends I hope you're happy without me even if I'm not fully happy without you I miss you, my old best friend
