How to encourage a person who has given up?

I to recently ask myself a question.Why am I here? Do I have a purpose other than just existing? I am still searching. Trying to finds one true self is extremely hard. It would seem he wants happiness (his way). Could he find others who love music as he does and and relate both of there talents to helping others with there music problems? Life sometimes does not go(our way). We need to step back from our daily routine and and try something (different).
Could you take him to a comedy club a music club anything that might take his mind off his boredom. He needs change (any change) bad. Repetition is boring. Seek therapy. Is he willing to sacrifice his problems for your love for him? He has convinced himself of these problems. Stay positive and turn all his negatives to positives. Good luck. pljames
