This is the first game that I have started to doubt myself as a player, tanking at low levels as PLD is enough to ruin anyone's confidence let alone someone with Anxiety. The best advice I can offer you is to join a FC and see if you can get a group run with them, this will help you bond a little more with the guild mates but also run at your own pace.

This community seems to be a massive split atm with some players that will be extremely helpful and then others that go out of their way to ruin your experience. Mostly because some of these players have been twiddling their thumbs for so long that dungeons are boring to them and they seem to forget that there are new players in the community seeing the content for the 1st time.

Hope you are able to find a small group of people that you can run with and enjoy this amazing game without the idiots ruining your fun
