On a strict diet and not knowing what to eat anymore?

I don't know what to eat, i'm starting to get frazzled and feeling on the urge of giving up. I don't know want to give up because i've already lost some weight. I just don't know what to eat anymore. The past week i've ate nothing but oatmeal, fresh fruit, and a peice of chicken for dinner. Every single day. What else is healthy to eat or cook?
