Speaking for myself as someone who was dismissive, my best contribution to the answers here is that it's reductionist to a seriously misleading extent. It seems like you have a couple of conditions contributing to your struggle, but it all gets reduced to "your number is too low." As others have alluded to, how much of that is your adhd? How much is from some condition you may have that hasn't been diagnosed because you have been unsupported throughout your life? I don't think anyone is denying that you have real neurological conditions that hinder you, they just doubt low IQ as being a meaningful description of what you're facing compared to something that gives a better causal explanation.
I appreciate your good humor since I think I came off as hostile
I guess my perspective is that we're talking about what OP wants to do in the present world, not what she could do in a hypothetical utopia (or just fairer society). So yeah, fast food jobs could be less terrible and should be, but at the moment they are absolutely not something to aspire to or even to recommend in many places because, again, they don't even pay enough to live. Maybe OP is still living for free with a friend, in which case I guess it's better than nothing, but in general it seems bad as a survival strategy.
