Apologies for the outburst/overreaction.

Words beyond being explanatory would be useless and being seen as self-justification, which is not the intent and I believe devalues the sincerity.

I don't plan to block you (plural) out.

That being said I believe I have caused an issue that will not be amenable/not still be in the backs of your (plural) minds, as such I won't try to reengage with the idea of friendship.

Had similar scenarios before (But I figured they didn't really like me in the first place) so I quit on it

I'd still be open to still being mutuals/acquaintances, or just enjoying/watching my work.

But I won't be planning to rejoin/join the/any groups or rekindle past mutual communications, at least on a 'me-towards-you' end, mostly in my own lack of confidence and the above-mentioned reasoning.
