Sorry, I don't know any PS CS6 tutorials. I haven't made icons in a looong time, sadly.

Oh, yes, not eating enough causes terrible headaches (I once fasted for five days or something and the first two were horrible). You're not getting enough energy (carbs especially) and vitamins/minerals. I hope you'll manage to eat properly. Take care.

Poor, poor doggie! What's with him? He seems so very scared.
