Is calling out of work because of personal family matters a good excuse?

I usually just say I'm sick, the day of and my boss is okay with it. But, I've been at this same job for 1.5 years and I always use the excuse "I'm sick" so I don't have to come in. I would like to have off tomorrow because I need to take care of some personal matters, and honestly am stressed to the max because of this stupid job. Is it okay to say I have personal family matters I need to deal with? or will my supervisor see right through it as me wanting a Friday off?
Yes, that is a good excuse.
No way, that excuse will not fly. Think of a different one.
