Want to suppress my appetite

What is the best appetite suppressant?? I am asking this because eventhough I wanted to lose weight I couldn't stop eating a lot :( I really couldn't resist those yummy foods.I wanted to lose weight however I didn't stop cooking and baking a lot of my favorite foods.So the tendency,I am tempted to eat a lot.

I did try dieting and even exercising to lose weight but everytime I started doing it I couldn't make it through.I stopped.I get tired so easily.I really want to supress my appetite.Sigh...it's really difficult to lose weight.
