Playing in Minecraft: Noob to Pro

The end

I just done some research and actually found out about this place called: The end. I wanted to make an end portal but I somehow couldn't so I went searching for it. I started digging and finally, after about 100 blocks dug, I finally found the stronghold. Then, I started turning corners but I couldn't find the end portal but I did find this super big slime and at first I thought it was a giant it magma cube but I heard the flop flop of it walking so I knew it wasn't. I was just about to go back up when I saw light up ahead! I turned a corner and there it was! The end portal. I was just about to go in when I remembered something: you needed to get some eye of enders to make it. I checked my inventory and finally found what I was looking for. i put my eye of enders into the holes and held my breath. Yes!!!! The end portal works! I quickly hopped inside and carved a carved pumpkin. I mined the edge of the end stone and jumped of into the end. Now, I've watched Minecraft story mode and I saw that you had to destroy the end crystals so that's what I did but first I had to collect more blocks. I first used up all the cobblestone and dirt I got from digging down and then used the diorite. Then I made a bridge towards the other obsidian platforms and tried to destroy the end crystals. It took so long for me to figure it out that I thought 3 days might have passed in the minecraft world but I finally figured out that you had to click the end crystals. i did this over and over and then made a crossbow to shoot the ender dragon with. Then I enchanted my crossbow and I got unbreaking III! I shooted frantically with the crossbow but still! It wasn't enough to kill the dragon. Finally, I tried to climb back up to the portal I could see. I collected my stuff, braced myself, and fell to the ground. You might think I might actually die but no. I brought a bucket of water with me and hopped down. From there, I could see the ender dragon soaring overhead. I shooted at it again and this time, I got it! The ender dragon roared and shot a blast of fire at me. I quickly darted away and collected the end stone. this was what happened for 40 minutes and then I finally climbed all the way to the portal and jumped out. I used the rest of my end stone to climb out. It was exhausting but I finally saw what I was looking for. I ran back home the moment I popped out and jumped into bed.
