I hear ya girlfriend, I am 51 and am now wearing extra large.
With me it all started a couple yrs ago when I quit Smoking. Now I am having a terrible time losing the weight. To make matters worse I am getting rashes & Pimples wherever I sweat, making exercising really difficult.
I wish I could be more helpful, just know your not alone. Keep up the good fight, and try not to lose your sense of humor.
How much aerobic exercise to you get each week? How about strength training? A diet high in whole grains, vegetables and fruit, with moderate amounts of lean protein combined with regular vigorous exercise alternating with strength training may really help not only reduce your weight but boost your energy level and mood.
