Ouch - I cannot imagine the fullness of what you are probably going through, but am doing my best to send a virtual hugs as I post this.
I would also encourage you to tell your Master - by not telling him, even for very good reasons, you disempower him, and you don't give him the option of caring for you at this time. Just my thoughts...

My commiserations on the passing of your Father. I agree with cariad. Part of a Dom's role is to support you and care for you in the times when you need his strength. He can't help you with things he doesn't know about.
