I think both posts are complaining about the same thing: policing each other's behaviors and expression of sexuality.
Maybe a lot of incels/gooners bring their lack of sex on themselves by not considering others desires or experiences. Until they figure that out, they have to be removed from common spaces. The loneliness epidemic is self-inflicted (and exacerbated by patriarchal capitalism).
There's a lot of good advice about emotional regulation here! I think there's some work that can be done around perspective, though- especially as you're coming out of burnout.
It seems like you're very attached to specific outcomes, like you don't know if you can manage or be safe if things don't work the way you imagine. Can you try to center your flexibility in these situations? Thoughts like, "this isn't what I intended but I can make this work," or "this will take a little longer now, but I still like doing this" (using cooking ingredients or computer work as examples). Feeling competent and capable leads to feeling safe, and positive self talk, even if it feels cringe at first, helps get you there faster.
