RANK/ONLINE ANXIETY. *

I have been struggling a lot to fight players online due to my anxiety levels getting so high it triggers my "Fight or flight" mode. It makes me very tense, and it discourages me a lot to play online. No, I am not saying I lose or anything because of the anxiety; in reality I find it difficult to find and challenge someone because my anxiety gets the better of me. I would like to know or see some clarity in this subject and question other players if they can relate or not and how do they deal with this high anxiety levels. I am currently in S rank with Anre. I have only went online/rank for 3 or 4 separated days. And I cannot find myself challenging other players on lobbies very easily. It really sucks because I feel this anxiety is holding me back. And I want to play a whole lot more against other players. I am currently a beginner (sort of)
