是I feel happy还是I feel happily?

是I feel happy还是I feel happily? 一个傻问题：i feel happy 还是i feel happily啊?啥时候用adv我搞不清了 "very" 忽然不会用了...是i feel very happy 还是i feel happy very much? I()(feel)very happy I Feel So Happy I Feel Happy I feel happy for you. I still feel happy without I feel happy.同义句 I feel good还是I feel well? I feel good还是I feel well I felt happy还是I felt happily
