Blacked out drunk and my dad had to babysit how to make sure he will not be mad

Yesterday my buddy and I headed to an outdoor party. Before then we stopped and picked up two bottles of vodka (1.25 litre). Once we got there we realized it had gotten shutdown down so while waiting for our other friends I drank some, around half a bottle in 15 minutes I don’t know what I was thinking. So I was chilling for around 30 minutes when I had to be walked home since I was blacking out. I thought my dad was out of town but no he was there so we tried looking for the key but couldn’t find it I was too drunk to even talk. My dad stormed outside and was strict with my buddy because he was afraid it was laced. So my dad brought me upstairs and he laid me on my side in bed. He told me that he’s never ever scene someone so drunk before and told my I was unresponsive and not breathing well. He had to walk back to my room every hour because I didn’t stay on my back. He doesn’t get mad at my sister for drinking but she’s a couple years older. I’m so embarrassed and sad that my dad saw me like that. I talked with him for around 15 minutes total today (sober). He did not seem mad but just worried and scared for me. What do I do to regain his trust and make sure he’s not mad and so that it’s not awkward between us two.
