Hi candidate,

It's very sad to hear that you feel that you have failed in life. My dear friend life is so long and gives a several opportunities to get back into the mainstream and lead from the front.

I am sure that there are chances that you might feel depressed or or get shattered  by disappointments or failures, but you have to move on as the past cannot be changed but the present can lead to a better future.

Keep faith!! Believe in yourself!!
