Japanese variants of "I am crazy"

• Boku, ikareta n da (m.)
  Atashi, ikareta n da (f.)

Can anybody verify the following phrases (red.)

• Boku wa kichigai desu yo (maskuline)
• Watakushi wa kichigai desu yo (gender-neutral, fairly formal)
• Watashi wa kichigai desu yo (gender-neutral, informal)
• Atashi wa kichigai desu yo (usually feminine, informal)

Comment: 'Yo' provides emphasis (kind of like an exclamation point) and also tells the listener that the statement contains useful information
