Are there really true friends??

Its been about 6mths since I last smoked a stick or two. But last night, to my surprised, I did'nt suceed upon fighting my own will. I broke my promise to God and to myself. I did smoked again.
Its about past 12 midnight when mom and I had a good talk about life and friends. I felt so depressed at the very moment. Asking why, in the midst of trying to be good, people cant see me through???...rejection and neglection here and there...Are we examined just in the physical outlooks???...Is having a pure heart doesnt qualify anymore for me to be loved by others???..Am I really good???...Or just pretending to be good?...How sad...Well, that only proves that life is indeed unfair in the eyes of man...But of course, I must stay strong, for I have still a strong God within me who pushes me through the hard times...
