I'm 33 and am on my 8th stomach virus in the last 7 or 8 months. more than half, someone else in my family also got. should i be worried?

Bad luck vs. problem: That sounds miserable! If multiple people in a family have similar stomach flu symptoms at the same time, it's a good story for passing around a virus, but may also represent food-borne illness, parasites, or even non-infectious cases of these symptoms. You could just have a run of bad luck, but best to discuss with your doc to see if testing or expert referral would help you.

It may not be: stomach viruses. After this many months - a medical evaluation is warranted. Take care.
