Extreme Lag/Blocks and Items disappearing or duplicating

As of last night, I started facing extreme lag in Realms. I checked my internet to make sure I had a stable connection, and my internet is working just fine. Currently, if I go to sleep in my bed, it takes 5 seconds for the character to actually start sleeping. When I place blocks, they place and the. 2 seconds later they disappear and the block is not placed back in my inventory, it just disappears. I put on a set of armor and it lagged all of my armor back into my inventory except it duplicated my chest piece. It seems to be getting worse the more that I play, or maybe that’s just because I was lagged off a cliff and fell to my death. All moving NPCs are also lagging, they will freeze somewhere and then 2-3 seconds later they will be somewhere else. This is particularly annoying when a Creeper is after you, they will be 14 blocks away and then all the sudden blowing up in your face.
