i'm still drowning while my head is above the water

This may be a one-off, and your using a modded client (Probs OptiFine which I know shouldn't affect it be I'm just pointing it out)

Thank you for your report!
However, this issue is Invalid.

Your game, launcher and/or server is modified.
If you can reproduce the issue in a vanilla environment, please create a new ticket - this is a bug tracker for the game, and not a support website.

• Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang Studios or the Bugtracker.

• Any plugin or resource pack issues need to be addressed to the creator of the plugin or resource pack.

• If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run extensively modified server software.

Also note that the current version is 1.16.2 - 1.16.1 is no longer supported.
