At what point should I just give up on chess?

You've posted about this multiple times now. You're fishing for answers you know aren't there. So I think you need to be told this more plainly.

You've posted elsewhere that you don't seem to have a knack for anything. I don't understand why you refuse to accept that you're not inteligent and you suck at everything. It's time yoy swallow that bitter pill. You already know it to be true, you continually go at lengths to prove your inadaquecies, yet here you are trying to scrounge up a pathetic reason to continue. You ought to just stop.

It's time to embrace what you've been posting on reddit at length for some time now. You have no talent. You're not good at anything. You're an evolutionary dead end. To continue grasp at this issue is a perfect example of desperation - that of which you asribe to those who persist at something without talent.
