I regretfully inform you that it has become necessary to tender my resignation as of Friday 3rd August. I have found my time here to be both rewarding and worthwhile, and I will miss working with my colleagues in WSFS. I am aware that I am resigning sooner than I originally planned, and this is solely due to a change in the schedule for house-hunting in London for residence during my degree.
How about this one:
Dear Grace
I regretfully inform you that it has become necessary to tender my resignation as of Friday 3rd August. I have found my time here to be both rewarding and worthwhile, and I will miss working with my colleagues in WSFS. I am aware that I am resigning sooner than I originally planned, and this is solely due to a change in the schedule for house-hunting in London for residence during my degree.
Thank you for providing me with this opportunity.
Yours faithfully,
Alexander Myers
