Well done for having councelling! However, don't mention the issue of the abortion to your employer. It's an extremely sensitive and personal subject, and frankly, has no place at work. It's your problem, your life, your issues. It's great that you have made the first step towards sorting out your problems, but it has nothing to do with your work place. Your boss will only be very embarrassed. Mention "personal issues" that you want to deal with, so you can get on with your life, but don't be specific. It's nobody else's business but your own.
