I am a thin guy and m not happy........

I suggest eating foods high in protein to help build up muscle - high in carbs to give energy for building up that muscle. Have you tried any protein shakes? www.puritan.com has excelent prices on all sorts of nutritional supplements, and often have sales of buy 2 get 3 free. Other than that, perhaps I could do a donation as I have plenty of padding to share ;) Best of Luck to you.
