when u are disappointed ,first you should try to find out the reason or reasons of it,then talk to a person about them who would be a successful in his life,next,try to talk with ur God,i am sure that they will be solved,in no way dont doubt about it

Either have trust in yourself ,or in God !! Stronger your trust in yourself, less you become hopeless.

(CORRECTIONS) What should I do when I feel disappointed and hopeless? Well, when you feel down, disappointed or hopeless, try to identify what makes you feel such. It helps when you know exactly what triggers those. Then, it will be good if you find a very close friend of yours, not just anyone, and talk about your thoughts and feelings with that person. Most probably, your close friend will be able to help you.
