Its okay not to be okay, is it really?

from the song ''who you are'' saying its okay not to be okay.

Is it really okay not to be okay because its hurting me so much I can no longer carry it over my shoulder.  If this is temporary then I would like to ask when will it end because I want to rest even for a bit.  I no longer have tears to shed or new prayer to ask but to help and guide me.  Is it really okay not to be okay when I can no longer see my purpose in life.  Will it end? When? How? Can it end now? I sincerely ask.
