Trisha, you've done amazingly well so far

Checking your profile I see that you're 162 cm, roughly 5'4, right? Have you given any thought that perhaps you are at a healthy weight for your frame? I realize everyone is different and at 125 lbs you may still have some fat to lose - but perhaps losing weight isnt what is required, maybe gaining some muscle mass would do the trick? If you replace 5 lbs of fat with 5 lbs of lean muscle you'll weigh the same, but you'll take up a lot less space.

As you are very close to goal, the loss will be slower, regardless of how you go about changing your body composition - those last 10 lbs can take forever - or so it seems.

As for the tiredness, we would need to know more - what are you eating, exactly? How much are you drinking (water)? It is quite possible that being very active you are not eating enough a) calories or b) carbs. Feeling tired, or 'bonking out' is a common occurrance if you are eating too few carbs for your activity level. Using www.fitday.com to track your food and activities is a good start - maintaining a Journal here is another great idea. With more information we would be better able to offer advice.
