Is it normal to not enjoy my first fight?

I had my first Muay Thai fight at age 17 last night and won by unanimous decision. . I didn't feel excited or amped up during the fight and didn't feel that happy when I got my hand raised. I expect to be really exited before and during the fight and happy afterwards but I felt sick.

Some considerations: I had some of the chinese medicine tincture that my GP gave me which included passionflower, codonopsis, saffron and ashwaganda. I also had a coffee 3 hours before the fight. I was also expecting to fight a bit harder than I did.

Just wondering if it's normal to feel this way because I didn't feel accomplished or rewarded even though my coaches and dad and friends said they were proud of me and I fought well.

If I'll always feel this way after fights I don't know if it's worth doing hard fight camps for fights in the future when I also have schoolwork to do...
