My brother does not know that he owes all his gaming accs to me

My brother is a very good player at LoL, he is currently Challenger and Top 100 in his role, and he has a very good win ratio being an agressive player. He currently plays with 6 accounts, each one in an elo different elo: bronze, silver, gold, platinum, diamond and master. He always changes his role depending on the elo, so he is able to play mid in gold, or jg in plat and so on. To win so much being so aggresive, he needs to know the mechanics of all the popular champs of all the roles, and hes good in them.<br><br>He was able to know how to play those champs because of me. I used to record all of his games, find his fails and mistakes, suggested him changes in his builds, runes, masteries and his playstyle. I was also making his VODs, where i was cutting the mistakess he made, and making VODs of his good plays. I was doing this for a long time, and i was very tired of seeing him getting recognition of all what i did for him, because he used to insult me, and to call me noob cause i was not good enough, but i never cared, cause i was happy to see him climbing and improving, and i never expected recognition for what i was doing for him.<br><br>He started his channel in yt, and started being more popular, and i kept doing what i was doing for him, and he never mentioned that everything he does is thanks to me. I got very angry, and i stopped all of what i was doing. his channel grew a lot, and he is very close to get a roster in a pro team of LoL. I am very sad seeing that he is getting all what he ever wanted, but i am happy too, because i know that he would not be where he is if werent for me. I can not tell this to anyone, cause i know hes gonna be very angry at me, and i do not want him to grow distant from me.<br><br>Edit: Wow, thank you all for being so nice and for your advice. I print screened all of what i have done, and i am going to talk to him tomorrow. I feel very lucky for having so many support, and i am so happy for all the kindness of all of you.<br><br>Edit 2: I talked to him, and he was very surprised, and he told me hes sorry, and that he never knew how much i had done for him. He told me that he is gonna mention all of what i have done for him, in his next stream, and hes gonna be making a VOD tomorrow with all of my work, so i am very happy.<br><br>Edit 3: Oof, did not expect this to blow up so much, hes making the VOD rn, and hes gonna do a collab with a streamer that is top 1 in his region and hes challenger 400LP. Thank you all for so much support, you have no idea how much your words mean to me, he just told me hes gonna ask for a shoutout for me in the collab, so im very happy for all of this.<br><br>Edit 4: I read each one of the comments, and i want to tell you guys that you are amazeballs, thank you so much for caring this much for me, hes gonna tell this to his chat in stream rn, and hes gonna give me a shoutout in the VOD tomorrow.
