i am deeply upset..plz help ??

i and she were close friends....i shared my every secret,my family problems,my past with her...i expected her to understand me after knowing all about me...but in last 3 months or so i irritated her with constant texts and ol even after she repeatedly told me not to....and hence she blocked me....from every social networking site...i made fake id with other name and sent her request texting her that that person(id with other name) is my good friend..she replied to that person like this "I am the most irritating person she has met,MENTALLY ILL,and she will take action against me if i dont stop bothering her" i am deeply upset after reading this....i understand her saying me irritating..but how could she say me MENTALLY ILL... even after i told her everything about me,my past...i expected her to atleast understand me...after what i've been through...i am deeply upset..seriously...after her comments...she wouldnt have achieved half of what i have if she were to encounter similar circumstances..she is blessed with good family and lots of good friends..i am not(i live in abusive and dysfunctional family and socially weak)..i have seen public humiliation..she has not...i expected her to understand me....i will never trust anybody again..never tell my secrets to anybody again....i feel totally worthless today..i hve no right to make friends..i am destined to be lonely...how can i forget her...like we never knew each other ???? i treated her as my sister.
