I hate waking up tired, although it's my fault

Yesterday it was like 5pm, time had went slow up until then (in like a good way, not a boring way). and then I started drawing (one of my interests). Time was suddenly 8pm! If it hadn't been for my family calling me down for dinner I would've forgotten to eat.

I'd been sitting still focusing so hard for 3h my head hurt. I felt so weird. I took a break. Then drew some more til 11pm. I usually go to bed at 11pm..So I felt really tired.

I got ready for bed. But then I got stuck in a loop of listening to my favourite two songs. Over. and over. til nearly 2am! In bed I was sat stimming happily. Yeah I was happy, it was great really. BUT i hate the feeling that comes on today.

This fricking tiredness. Not to mention I hate waking up later than normal. It's out of my routine. I woke up at 7.22am (I normally wake up around that time) without an alarm. I considered getting up but I felt SO tired. So i went back to sleep.

its 10.11am for me now. I'm sat in bed kinda panicking??! Ahh. Why. I feel more rested now but also like I lost time! It's sunday so it's fine. But also I wasted my last weekend day sleeping in. I wanted to wake up earlier as I normally do. Why didn't I just sleep and do those things today?! Urgh! It's messing up my internal routine and I feel kinda stuck in bed until I figure out a new routine for today.
