Everyone goes through personal issues of some  sort during their lives. When I was just starting my career in the corporate life, I was always told not to mix business with personal problems. Personal issues together with family problems, life changing situations, emotional difficulties, illness, and even one’s sexual orientation, can impact your job and the ability to  advance on your career. Of course there’s no need to share specifics unless you want to. It’s your choice. But sometimes when you let others know about the circumstances, it negates gossip and sets your co-workers’ expectations properly. Beating yourself up will accomplish nothing except low self-esteem and this will only add up to difficult circumstances. Accept the fact that you won’t be at your best in the office during this time.
