I used to have a brilliant memory.I could remember memories from the time when I was 2 years old but now what's happening is that I have been forgetting some normal things e.g. Spellings,formulae etc and this started when I was 13 and I didn't have that much problem but from last year I kinda can't remember what happened when I was 12 or who taught me in class 1st I earlier remembered it well but now I am just forgetting every year of my life. Having a great memory then suddenly forgetting my past is just too much.I just cry and cry. Hope any suggestions will help me.
