dyeing/changing your hair with anxiety

I´ve been wanting to change up my hair for years and in the past couple of months I´ve been feeling extremely disconnected with how I look but I still can´t go through with changing my hair because I´m too anxious to do anything about it. My hair rn looks kinda okay but I just don´t like it anymore but I´m afraid I´ll dislike the way I look even more :/

does anyone have tips on how to overcome that fear? I´m tired of looking like this :(
