Working Girls- Advice Please

Most of the lovely bloggers that I meet in here are working girls. I don't know if you have experience this kind of thing but just the other night I did help my sister rushed her research paper and I helped her.  I was thinking it's okay I can sleep in the morning so I helped her until 3 am.

Morning comes and I tried to sleep, my body is so weak tired and want to sleep but I just cant, I tried to relax my mind but I just cant help but wonder on my mind. My eyes are close but my mind is wide awake. I ended up having a terrible head ache.

any advice on what to do in times like this?
