personally, I've never lasted more than 6 months, so I think it's GREAT that you are still working away on your plan after 8 months, and that's regardless of the amount of weight you've lost. Staying with it will be the thing that gets you there, and when you get there is less important than just getting there.
and yes, definitely try to get into more exercise - with 22 lbs gone, it will be much easier than it would have been before - just do the same thing of taking it small steps at a time, and you will get yourself there on fitness, the way you are on weight.
