Your body is probably getting used to the fact of you reading before bed and staying up too late, so it's hard to sleep early. Or you could have insomnia, who knows?
Actually, before I wasn't reading. Infact, I hadn't ever liked reading before this year and I'd usually find myself awake even before I started picking up the habit to read before sleeping. I usually find myself being too hyper sometimes *happens very little but gradually as I grew older, I'd find myself more emotional and more *hyper (maybe) than before.
I'm exactly like that! I fall asleep really late too I share a room with my brother luckily he sleeps at like 5-6 AM so I fall asleep first but recently he been sleeping in living room and earlier. I also can't sleep without the lights on since I get scared but since everyone is already asleep I have to turn it off. But I actually do understand you cause I do that too, I either watch YouTube or read manga until I'm really tired a could fall alsleep by closing my eyes. I've been trying to sleep earlier too.
Just a random question I wanted to ask... It's just that I have problems sleeping *even though I'm only thirteen. And when I try sleeping, I wait and wait for the total of two hours when I finally give up and feel bored so I grab my phone and start reading... After that, when I actually try to sleep, I sleep. But on days when I don't to pick up my phone to read a bit, I just can't sleep. I'd stay up for hours and then, BOOM sunrise. And the next night, I still wouldn't sleep until four in the morning.
