I just wanted to mention that I am 22 and in basically the same situation as you. I recently permanently deleted my league of legends accounts, epic games account, origin, and permanently removed all multiplayer games from my steam and uplay accounts (since I don't typically sink 100s of hours into single player games). Today I really wanted to play some csgo really badly but I permanently removed it from my steam account and it prevented me from going back into it. When I quit league, I relapsed a few times and told myself that I was going to level a new account but even playing normals after a long time off felt god awful and not to mention not having access to the champs that I wanted to play. I hope you permanently delete your accounts through support because it really does help.
