No matter who rejects you, don`t lose touch with your higher self, with the higher powers, with anything that you can find which is of the light, that will give you strength in those times when you feel so lonely.
There is only one issue: man`s lack of experience in feeling his Divine self and his innate connection with the Divine. All other issues stem from this.
It`s about sharing. You just give what you have to give wherever you go, and you let God handle the rest.
