Hello, Kate, and welcome.
I think your goal is reasonable but challenging, about 8 pounds per month. Keep in mind that everyone hits plateaus; the important thing is to stick with it and not let the scale not moving discourage you from doing what you need to do.
One hint I could give is that you may want to include some protein and some healthy fats in your diet. These will both keep you feeling fuller longer and will also help your body burn fat.
Also, make sure that whatever you are doing is something you can stick with for a long period of time. Ideally, you should eat the way you can eat the rest of your life, not just as a "diet" you will go off of eventually, because then the pounds will come back.
Have a look around the site; there are lots of threads and posts with great advice! Feel free to post and chat; we are looking forward to getting to know you
