UPDATE: recently found out that I (17M) got into my brother's (19M) former dream university which he did not get accepted to last year, feeling guilty about really wanting to go now

Update to my previous post
On Saturday I was able to speak to my brother and tell him that I got into the university. He was really happy for me, like a lot of people said he would be. When I told him I got in he gave me a huge hug and was really excited. It was such a huge relief.
He asked me if it was my top choice, since he didn't know I had applied. I told him it was and he said that we have to celebrate then. He told me I didnt seem excited enough and I should be really proud of myself, and he asked if it was the shock of just finding out.
When I told him I find out a few days ago and he was the only one that knew he asked me whats going on, because I wasnt reacting to the great news like it was great news. I admitted that I worried about telling him because I didnt want him to be mad.
We talked about it and he basically said what everyone in the comments said, that he's proud of me and happy for me. I mentioned that I got into a different program than his and my requirements were lower, and he told me to not downplay my success and to stop worrying about him being mad because he wasn't. He told me that when I told out parents he wanted me to be more confident and proud of myself, because I did something great.
Yesterday while we were hanging out at his buddy's house he told me I should tell them the news, when I didnt want to because I hate talking about myself he asked if could tell them, which I told him was OK. they were all happy for me too. Honestly, he's reaction was better than I even hoped for, but looking back I should have expected it from him because that's always been the type of brother he is.
TL;DR told my brother I got into the university and he incredibly supportive and happy for me. He told me not limit my success to make other people more comfortable, and that he was proud of me (which meant a lot to hear).
