takes away my motivation...

I have been having headaches for ages, i sometimes get a pain by the presure points by the side of my eyes perticularly the right. However i seem to always be having a tingly sensation across my forehead. I am not sure whether it effects my behaviour because i while i am having these headaches i sometimes act very stupid and hyper and i know that i am doing it. It also makes me feel lazy because it takes away my motivation to do things ( if i had any in the first place) simple things such as tidying and cleaning and studing etc. I am 21 and have had these headaches for a very long time. i have seen a doctor and he said that my blood presure was slightly high however he said that could be anything. Years ago the tingling in my head got to the point where i felt so dizzy that i had to sit down but it quickly passed. I want to request a ct and mri etc however i am afraid because i have read other peoples problems and they seem to be having no luck in finding the answer. i also sleep a lot
