Dear mansi ji,
We are travelling in same boat.. i can understand how much tough its to manage.. lot of frustation, anger etc.. but with my personal experience i would like to tell onething.. how much u think abt all these things.. that much pain we will have.. so better try to divert your concentration..best way would be as Ganesh ji suggests read Saisatcharitra whenever u like and think of babs stories or listen Sai arati.. its gives immense power and happiness..
Friend is one who forgives u before u say sorry, understands u before u explain, waits forever 4 u, stays on when u say leave me alone... The one who will be always with u in every happiness and difficulties is your true friends.. rest all passing clouds.. dont waste your precious time on them..
Baba will bless you....
Allah malik..
