enjoy myself

  1. I enjoy myself.
  2. I enjoy myself in sharing others’ hardship.
  3. I enjoy myself when sharing others’ hardship.
  4. I enjoy myself to share others’ hardship.
  5. I enjoy myself for sharing others’ hardship.
    Are all these sentence correct logically?

As a rule, the verb ‘enjoy’ needs an object or a reflexive pronoun, not both. So, I think ‘I enjoy myself’ or ‘I enjoy sharing others’ hardship’ would be acceptable.

Beeesneees,
Can I not say:

  1. “I enjoy myself in sharing others’ hardship.”?
  2. “I enjoy myself to share others’ hardship.”?
    Please explain the grammar involved?
    Thanks.

No, you cannot. Anglophile has explained the grammar.
