Definitely depends on whether your having a surgical or medical abortion. I've had two medical abortions in the past, both at around 5/6 weeks pregnant. I bled for around a week then was spotting on and off for the next couple of weeks after that. I can't say how you'd find it mentally because everyone copes and reacts with things in different ways. Personally, I was fine with it. It isn't a nice situation to be in at all but I didn't get myself too upset and worked up about it. I wasn't escorting at the time of these abortions but after the bleeding / spotting had stopped if it was now, I could happily go back to escorting straight away. I didn't get any other side effects other than the bleeding and the only pain I had was the initial pain when it all "starts" to happen a few hours after you take the pill but they give you painkillers (usually codeine for that) and for me the pain didn't last that long.
In regards to surgical, I only personally know one girl who had a surgical abortion. I'm not sure how far along she was but I remember her having a lot of pain afterwards for a week or so after it.
