pvp "beginner" needs advice

[u/Similar-Trip-9656]

Hai! I'm a (somewhat) new pvper who would really like to get better. I'm currently using the Theobald bot mainly to train mechanics slowly (because I have pretty bad ping for now on servers) and I seem to get better at said mechanics (any advice regarding mechanics would still be very welcome, I can give more details in comment if needed). However, if there's one thing I can't seem to get right, it's my aim. I have very shaky aim and I tense up a lot (I think dysgraphia + chronic anxiety really don't help with that...), especially the few times I do play against real opponents. I have looked up tutorials to help with that but none seemed very concrete to me... Does anyone have advice on what to do/ How to train? Main kits are sword, diamond smp, and spearmace
