Please don't avoid words or speaking situations. All forms of avoidance will feed your anxiety. A better way of dealing with blocks would be to learn easy onsets to prevent blocks from occurring, or In-Block Corrections to move through a block. If these techniques are unknown to you, I highly recommend the [self-help book](https://www.stutteringhelp.org/sites/default/files/Migrate/book0012_11th_ed.pdf) from the Stuttering Foundation
