Stay strong...making decisions on your values and not on a "guilt trip". There is a fairly large difference here in the use of the words I've chosen versus the phrase "feeling extreme guilty"...

-Guilt trip is to try to make someone feel guilty.
-Guilt is a feeling of having done something wrong.

...So a guilt trip is literally trying to make someone feel like they did something wrong. Reread these words.

Just because you decide you are unable to attend...do not allow others into convincing you have done something wrong...There is nothing wrong with that decision...it is yours to make.

Know if you went and stole a purse from the local store...you would feel guilt for having done something wrong...

Honoring your father and mother does not mean you have to be at this event. I'm assuming your father is worth honoring...so a card and call...is honoring him. Making a decision that is good for you is not dishonoring him.

I guess I've gone on long enough...I think you get my point about "Guilt Trip", Guilt, and Honoring...
