Same here. Recently my mother fell sick and had to go stay in the hospital. It was far away from home and she didn't want to stay alone. I had to go stay with her in the ICU. At night they don't allow visitors to sleep there so I either had to stay up all night or go out to sleep in the family center. But my mom wouldn't let me leave her all alone. Sometimes I would sneak out when she fell asleep. I would get about two hours of sleep before she calls for me to go back up. I also had to starve because I didn't have any money to get food. While I stayed with her she keeps saying things that I didn't want to hear. She kept saying that if she dies I have to take care of my younger siblings and become a mother to them. All I could do was cry and listen. For a whole month I was exhausted, but I still can't sleep at night because of worrying.
I mean I've been staying up late at night long way before that. I would stay up till four or five in the morning anyway. I just somehow can't sleep. I close my eyes and it hurts my head because I my brain would thinking just random stuff. I feel like my mind just keeps thinking and running while I sleep. I wake up with headaches every day because of this. But with the last month things are worse because of more worrying.
But the thing is that somehow I could sleep better in the day time. I have no idea why this is happening though.
