Cant sleep if its after 12pm?

for some reason recently if it gets any later than 12pm say if i go to bed at 2am i cant fall asleep its like im tired at 12pm and once its hits 2am i go into overdrive and am not tired anymore? but im a night owl ive always stayed up late and went to later at like 2 or 3am. but now im afriad i cant even go to bed at 1 and risk not sleeping! now iv NEVER had any trouble sleeping. ive always been able to go to sleep/ sleep well. but recently i tried staying up all day just to see if i could do it i only made it 32hours. but ever since (Its been a week now) ive had trouble sleeping?! It really f.u.ck.ed. up my sleeping?! i dont know why. even if i go to bed at at normal time i cant fall asleep? why? is this because of the sleep deprivation attempt?! i feel like such an idiot. if i knew it would cause me to have sleep insomnia i would have never done it!
