since you have a valid emergency reason, you can have the validity extended either at the philippine embassy or at the dfa office in manila.

would recommend the philippine embassy doha though as it's faster there, meaning it doesn't take forever, unlike the dfa, and no appointments are needed. published processing time for dfa manila extensions is three working days, and after that you will need to get an oec as well. this would eat up a lot of your very precious time if you decide to have it done in the philippines since you will only be there for a week and more importantly, you need to attend to your father as well.

you might opt to apply for renewal the embassy at the same time. they will only cancel your old passport once you claim the new one.

yikes, it seems my response is too late. i hope you were able to extend your passport's validity and wish your father gets well.
