Its mainly because i am still comparing myself now to the detail oriented me of the past. I used to never miss details like that, now i dont even notice them till later. I am trying to adjust my self expectations as much as i can to how my brain works now. Ill get through it, just takes time.
I used to be able to picture a whole computer program in my head and the code just flowed like a river. Now i have to constantly check the manual and i cant remember what i was working on from one day to the next.
Its just gonna take time till i settle into the new me 
Thanks for understanding
