Why can't I generate sincere inner cry in Heartfulness feeling numb failure?

The Heartfulness literature mentions generating a sincere "inner cry" or feeling of intense need. I try to force this feeling, but I remain emotionally numb or blank. I feel like a failure because I cannot generate that authentic feeling about my own deep sadness and depression. My name is Sunidhi from Jaipur, DOB 20th April 1990. Time: 3:55 PM. Is the ability to generate a powerful inner cry necessary for progress, or is the effort itself enough?
