Good fight brother, but you need more work before you step back in.
Work on your jab, and watch his left. You began a lot of exchanges with your right cross or hook but not as an accurate counter just whiffing. Put those behind a jab. It seemed like your lead hand was non existent, and his lead hand was landing at will. Spar with people who can give you a good stiff jab and lead straight to work off of.
Look on the bright side, not only do you have the cajones to get into the ring but you also now have this tape you can analyze.
Do it unemotionally, learn, improve. You got this.
On the dietary front I'd ideally get there early enough to have a full meal 4 hours prior to fight time. But don't stress that stuff very hard. You need to work on your lead hand and defending the lead hand.
Also, you're going to want to react to what Woldog is saying with anger or pride. That's natural. Don't do that. He's right, he may not be polite about it but that doesn't make him wrong. You need more work and a serious devoted coach who's at least willing to put their reputation and corner work behind your brain health before you book another fight.
