I have that sort of problems too, but only since some months ago, due to depression. It causes lack of concentration. And yes, it sucks.

From childhood’s hour I have not been as others were—I have not seen as others saw—I could not bring my passions from a common spring— From the same source I have not taken my sorrow—I could not awaken my heart to joy at the same tone—
And all I lov’d—I lov’d alone. E. A. Poe
