How to move on from losing a tournament?

Hello, its been my first time joining a dota tournament and its held inside our university. I am not familiar on how these games go since I've only played pubs before. I've made a team with my course mates and managed to reach upper bracket finals of the tourna. Unfortunately we lost and moved on to the LBF and lost again. Even after the preparations I've made I still blame myself for our defeat. Im an archon 5 and my teammates are all Divine players and im their carry. I feel pressured so i tried to improve myself in a span of two weeks, countless hours watching replays of our practice matches, but still i couldnt fulfill my role. My teammates are not blaming me, I just feel bad because I am the carry and i really felt i had no impact in our last two matches in the tourna. I felt like my performance on the games we had won are just flukes. Now im questioning myself if had made the right decision on joining the team, since i am sure that there are a lot of better players on our department. I am an electronics engineering student btw.

Sorry for the long read guys, I just really need someone to talk about my frustration. Thanks
