Guys, why can’t my mind rest?

Why is my mind so busy, so full of information, that i hardly have the room or capacity to move amongst that information and crazy hectic-ness? Why can i not seem to categorise and systemize it all. I very much like systemizing and in many ways I do, but why can i not order my mind? I just don’t know what to do. I am overwhelmed, and find myself in tears, a lot. I cannot think straight. When I try to think/read/study I cannot seem to take the dam information in and I cannot remember things. My memory has always been such a problem for me. Why is this???!!! It drives me insane. I used to be so smart, and quick. Not that this relates to memory I guess. I so, so, so wish I had a bloody memory for things. My bad memory makes me very angry and frustrated and it holds me back so, in so many ways, in my ultimate pursuit for further knowledge/study, dam it!

Is it simply a normal process of the realisation and acceptance of the the newly discovered AS ownership? Is it the fact that my mind is scrupulously re-hashing the little memory bank I do have of my whole life, and is busy systemizing these and ticking them off with my now new found knowledge and reasoning… Please someone advise…I am struggling…
