Abortion

I recently found out from a home pregnancy test that I'm pregnant. I got ahold of the abortion clinic in my city and I've set up an appointment about 2 weeks down the road to go through an abortion process. I'm 16, there's no way I can take on the responsibility of a child. I was wondering if anyone who has gone through this could give me some advice on what to expect and methods of coping after the fact? Thanks so much!
