Dear Ashwin,

Due to a sudden setback in my health, I find it impossible to manage effectively with the duties and responsibilities of my office as the president of the organization.

With deep regret I resign my post as I am leaving for a seaside resort and may not return for many months to come.

Convey my best appreciation to all the members for sincere co-operation offered by them in the performance of my functions as the president.

Yours sincerely,
(your name)
