Be happy you're not addicted anymore, throw a party and enjoy real life.
After that, you can choose another addiction, preferably another MMORPG or maybe an online shooter.
If you don't want to play another game you should find another hobby or you're not really sick of rs. What you probably mean is that you're sick of playing rs the leggit way.
So, like the people above told me, sell your account and start over with a nice starting budget. Or bot and enjoy getting rich and maxed the easy way.
I wouldn't suggest joining a clan. they really suck you into the game, unless that's what you want. And I can only speak for myself, but i find no more fun in clans since Jagex is promoting RS clan life. Makes me feel like a 13 year old tool.
EDIT: love your signature.
