Ranked anxiety.
Recently I've got the urge to try ranked again but like the title said, I have a the "Ranked anxiety". In the past (I think 4 months ago) I've played three ranked games with friends and lost all of them so I decided to give it a bit of a break. I still had my doubts about doing ranked at that time but my friends made it bearable. Now I fear playing ranked and I have no friends who wants to do ranked with me, don't want to do ranked at all and some that would help me but they take a very, very long break from LoL (I blame Overwatch). While "talking" to my therapist (looking at the void in my room) I've understood why I have this anxiety. The reason I came to is that I'm afraid of the reactions of my teammates to me. Although I can play every role decently and even very good (beside top lane) I'm afraid that I'll make a mistake that may make us lose the game in an instant and I'll get flamed super hard, I know that no one is perfect but I horrible after making a mistake and I'm being harsh on myself afterwards. But what I find weird is that in normals and in real life I mostly ignore it, sometimes I'm rekting them and sometimes I even join along for some reason. But in ranked for some reason I find it much more harsh and I don't know what to do when it happens, I feel like no matter what I'll do it will backfire at me in some way. After all of this boring stuff I wrote I would like to ask you a question. How can I deal with this anxiety? What could help me in my scenario?
Thanks ahead for helping me, I'm sorry for taking your time with this long story of mine and I'm sorry for any misspelling that may be in here.
