i don't know what happened to me either, its like suddenly the clot in my mind just cleared..
one night i was crying and crying and i asked myself why am i crying..and tats bec im remembering the past, yes i treasure those past memories but i don't hv to cry over them..he is now gone and sulking will not change anything.
And i just decided i didnt want to waste my time mourning over wats past, i want to live in the present..i hv accepted what is now and i live for myself. i don't know if this is confidence but i certainly hv a clear mind now..
So... there is light at the end of the tunnel, the only time u don't see any is because you have stopped walking.
