Im Getting Worried

[bigblue1212]

my leopard gecko hasnt eatten for 3 weeks now and hes barely active.......even with the food right in front of the thing it wont eat at anytime. When it walks around it kind of looks like its struggling. I dont understand why it wont eat the conditions have never changed in its enviroment. Its tail is still in good shape though but 3 weeks without eatting is really weird.
