Simon you probably did nothing wrong. This stuff messes with our head so much that we cannot guess what it right and wroug with us anymore. If you have something to sleep with that makes you feel safe use it no matter how silly it may seem. Special blanket, stuffed animal, picture, song, or a night lite. It may help calm you enough to get some rest.
Lots of us kids spied on our parents. Especially if there were disagreementss going on. I spied on my dad some when I was little. Sure it was probably wrong to do but I was just a kid. What did I know? My dad spied on me. Kids are curious, parents are role models and we watch them to see how we should behave in various situations. That is just normal. Your not weird, freaky or even odd. Your ok. Your parents might be weird but that is kinda normal too, especially for the people here. Hope this helps but without knowing anymore about the situation that is all I have. Thanks for hte post.
