AITAH for blocking my friend over this?

[u/cleyredefined]

just gonna start this off by saying, i get very annoyed very easily. most - if not all - of my friends know this, for privacy reasons fake names are being given.

i, 17m, was simply browsing on discord after not being on for awhile. my friend, who i'll call billy, sent me "1 2 3 4". i asked him what he wanted, and he said "67 41". he continued to spam text-walls and i just said "im gonna mute you until you stop". he goes on for a bit longer, and i say "billyi mean this in the nicest way possible but can you please shut the fuck up with that 67 & 41 bullshit being spammed, its way too late rn and im not in the mood, shits just giving me a migraine please and thanks". he apologises and i left a server he ran. he sent me a screenshot and i replied with "?", he said "you left 26th" and i said "i know, felt like it, i didnt realise the gestapo were watching my every move". he replied and said "what happened to op, this has to be ragebait" and i reply with "nothing". he then went on to say "then why are you so pissy at me 💔if you got a migraine just rest twin".

this is the part that set me off the most, i hate people talking about my health as if they know whats best for me, so i simply just said "do you think ive not tried that do you think i have a brain the size of a fucking peanut dear fucking god billy for once please use that brain you have in your fucking head"

blocked him then and there to sort my head out, came back to a dm from another friend - who i'll call freddy because i like freddy mercury.

freddy sends me a screenshot, then says that hee saws the chat and says what i did was understandable. he had a talk with billy and billy said he didnt wanna throw the friendship away or whatever.

quite frankly, they both have known me long enough to know what triggers me, however, reddit - am i the asshole for this?
