I need more sleep!

I wish I could be sleeping right now. For the past two days, I haven't had a goodnight sleep. On Monday, my dad was being weird and crazy. He kept letting out big "sighs" at 2 A.M waking me up and continuing to do it for another half hour. Every time I'm at the point when I'm about to fall asleep or I think he would finally stop, he either cursed or sighed loudly from his room. Scared the living soul out of me. He said he have so much on his mind, but he's not telling anyone of us what's wrong, including mom. Then last night, I was waken by crying cats at 3 A.M. It sounded so creepy, yet ANNOYING. Sounded like they're having some kind of funeral at my yard. Then later, I heard them fighting and continued on crying. I wanted to cry myself because all I want to do is sleep! Please let me have a goodnight sleep tonight :[
