You have a life purpose even when it is difficult to see what that is.
Do not think about the past and the days months or years ahead.
That will confuse your mind. More, try to go within. Find your very essence, your inner voice and be in the moment the now.
There are days when you will feel like giving up on others due to their behaviour or temperament and we see and feel your frustrations and heartbreak; your tears when you think no one is looking.
Its what life is about: feeling, expressing, being.
Don't think it is wrong.
Nothing is out of place. Everything is exactly how it should be. Unfairness and sadness to you is satisfaction or gratification to another.
The universe takes care of everything in time; you will see that and light will never diminish to darkness. So in that knowledge keep shining, keep loving, but most of all be thankful for the divine truth is in everything waiting to be awakened.
