^^ Yeah. Just sounds like a case of the traditional casual approach to drugs not quite working out. We all do that. I do it at least monthly usually 8)
Psyches really don't work so great when doses are split. Generally speaking (*waves at ed

*) anyway. Psyches seem especially odd in this regard. It's the one class of drug where I honestly think slightly overdoing it is always gonna work out better than slightly underdoing it. If you undershoot the mark you get nowt but weird bodyloads and annoying stimulation usually so are tempted to redose... which means you spin out that weird bodlyoad and annoying stimulation for even longer with maybe a brief window into Happland inbetween if you're lucky. Most annoying. But probably is better to be underwhelmed than overwhelmed with psyches - especially if not hugely experience with 'em yet. Or maybe not... I'm still gonna go with not actually.
I know exactly the feelings you describe. Psyches really do that heaven/hell thing to a tee. If you've had a mixed (at best) result then you interpret everything negatively. If it went well the exact same things seem like positives. It's annoying but the best option really is to just let it ride out and sleep it off - not long to go now and the stimulation will be over and you'll be able to sleep just fine
Psyches can make you feel all kindsa ways and they can put you in all kindsa moods. Sometimes you wanna just lock yourself away and gaze at your navel, sometimes you wanna tell the world you love it and give it a big ol' snog, sometimes you wanna spill your soul, sometimes you wanna say nothing and dissect your soul. Sometime you wanna wank yourself into a stupor and giggle at the pretty things. All things to all men at all times are psyches. Often all at once. Or not the thing you hoped for. Practice makes perfect
