Game Lag and Character movement

I have been experiencing lag and my character moves on its own it has been happening on and off for a while but since the new update its worse and now when I harvest anything or break blocks, I have to linger for a few seconds to collect the items. I have updated my drivers and everything i can to improve my game playability, but the issues still remain. I have updated and reinstalled everything and it is still happening, I used to love relaxing in the world of Minecraft but now its unplayable and I no longer want to play. I sincerely hope that some issues are addressed soon.
