Urge to eat but no appetite

Don't know what's up with me lately. When I feel hungry or have some cravings for some food, I go right ahead to eat and satisfy the urge. But the strange thing is that the moment the food is there, I don't feel like eating it. It's as if I've lost my appetite right away. I didn't take any appetite suppressants, so I don't understand why it's happening.

Maybe I just need to relax, take deep breaths and let things go a bit easy on myself. Hopefully then I'll be back on track. In all things, not just this appetite thing.
