You still haven't really answered the question.
What kind of Psion?
Kineticist, Egoist, Nomad, WHAT???
If your GM can deal with it and you like playing a pure blaster, go Kineticist. I'm come close to pulling out my hair over the one I have in my game (Energy Missile is arguably over-powered for a 2nd level power), but I can see where it would be fun to play one. Just stand around flinging whatever kind of energy you need at the moment.
Shaper if you like using Constructs like you'd use summoned monsters or animals.
Egoist can be interesting, but most people with that kind of idea go Psychic Warrior.
Telepath is best for non-combat role-playing and problem solving.
