Do I get a graduation party?

I had a baby when I was 16. I was really struggling to juggle full time school, full time mom, and full time work. So I decided to get my ged. I passed in February. All my cousins my age are graduating in May and having parties. My grandma (bless her heart) wants to throw me one. She believes that even though I didn’t do it the traditional way, I still graduated. But o don’t know.. should I have a party?
