Being a human being is so hard. So much pressure from life, goals and achievements being hoped to achieved. Friends can betray at anytime, human beings can bear false witness, family can discourage. Writing a book can be painful if you're not on the creative side, various judgements being passed on your book, discouragement, competition from other writers. All these most of us face here but obviously cannot share it. If you fall in this category, it's alright, don't loose hope. At the end of the day, success is assured for us.
