Not working right

I have a lot of things I need to get done but I do not know what to do first. I just got my computer back from my son who was using it to watch cartoons on you tube. I was mad because he was using it but his computer is messed up now, my husband has been trying to fix it since last night. I hope he can fix it soon because I do not want them to use my computer because I have a lot of things to do here on my computer but right now my mind is not working right. My mind is so tired from thinking it needs a rest and I need a rest too. I think in a few hours after my nap my mind will start working again.
