Moral Dilemma

My sister and I are both graduating from college this year. I am graduating from a university, and she is graduating from a community college. I think this is a big achievement for both of us, and I am very proud of her. But I think she doesn't like when I talk about graduating. Not, that she has a problem with it. But she is graduating first. She will be graduating in a few weeks actually. Less than two weeks from now. I will be graduating in December of this year. I have one more semester of school. We have a family group chat where we talk and share our accomplishments. I just found out that I am graduating with honors/distinction. Cum Laude to be exact. I want to share it with our family in the group chat, but I don't want to seem like I am outshining or stealing her moment. But I have told my family that I want to graduate with distinction. It has been a goal of mine, and I am happy to have achieved it. I want to tell them that I finally know for a fact that I am going to do it. It is based on your cumulative GPA before the semester you graduate. I am so excited I feel like crying. I failed two classes when I dropped out in 2017 because I did not officially withdraw. I was discouraged from going back until 2019 came around and I changed my mind. I pushed through and was able to bring my GPA up to almost 3.4, and I now I am graduating cum laude. I am so excited because I have gone through so much shit. I just want to share it without seeming like I am stealing her moment.
