insecurity (N) – not confident with oneself
feel badly (VP) – "The adverb badly is often used after verbs such as feel, as in I felt badly about the whole affair. This usage bears analogy to the use of other adverbs with feel, such as strongly in We feel strongly about this issue. Some people prefer to maintain a distinction between feel badly and feel bad, restricting the former to emotional distress and using the latter to cover physical ailments; however, this distinction is not universally observed, so feel badly should be used in a context that makes its meaning clear."
