Group content anxiety

So let me start by saying I've already done a few dungeons with other people but I was with a friend at the time who helped me out a bit.

Now however I'm trying to do dungeons with only random people and... my anxiety increased.

Especially since I've mainly been playing Paladin and a bit of Scholar (been testing out all the different classes to find my favorites) so when I do dungeons I'm the tank or the healer.

I tried doing a dungeon yesterday with others as Scholar and messed up causing a party wipe (tank did w2w and i fumbled my buttons as well as not realizing my fairy wasn't summoned) and this incedent made my anxiety worse.

I know I'm still pretty new and mistakes will happen but I'm feeling nervous about even attempting dungeoms with others again.

Guess I'm just looking for tips? See how others deal with anxiety around healing/tanking or just group content in general.

(btw in case any tips are related to controls I'm on Switch 2 so using controller)
