I can't drink potions in Minecraft and I can't use a map either. It's a glitch for me only me. please fix it! My username in Minecraft is SammieRuffs

So probably a month ago I was playing Minecraft and I was trying to download addons and stuff and when I went to hive the water looked different and it felt invisible. And then I went to my world and someone gave me a position and I couldn't drink it weirdly. And then I went to someone's world survival and I got a map and I couldn't use it. And I couldn't see my hand in Minecraft (Minecraft hand skin ya know)
