Just got rejected from a company for a summer internship after making it to the final stage. I thought I had really solid interviews. Any tips on getting back in your feet and doing better next time?

I felt like I was a perfect match for what the company wanted. The company had the values and culture and field I was looking to get into so I was majorly disappointed when I was rejected. The only reason I think I didn't make it was because I sent an email that I couldn't meet for an in person interview when they asked me but then followed up immediately after a day to say that I was able to work out my schedule and come meet. The interviewers said I had great answers so I really am stuck, I don't know what I did wrong. This would've been my first internship so it does hurt a little bit. How can I keep my head up and move forward? Any general interview tips to ace the next one?
