I think you are spreading yourself too thin. I always find my characters struggling when they try to raise too many different skills at the same time. Get awesome at a small number of skills and then add more after that. I would focus on just illusion and stealth before adding on all of those other skills. Do all of the illusion perks and all of the stealth perks except only do 1/5 on sneak. Once you have leveled those to 90+ you can start adding other skills.
