Do you believe in free will?

[Perhaps]

It seems like you haven't put nay thought into this at all. You are essentially putting forward a circular proposition.

1. I exist in reality.
2. Reality exists in my mind.
3. My mind exists in me.

You premise itself is illogical. You cannot hope to prove anything using this premise because proof presupposes an objective existence of reality.

You missed my first premise.

1. The mind (which gives 'me' the ability to have identity) exists in the true material world
2. The mind creates reality
3. I (the mind) exist in the reality which I create
4. Thus, because I have created it, I have free will in my reality

This would be analogous to an individual who is blind. They exist in the 'material world', yet their perception creates blackness all around them. They live within this blackness.

The real question to ask here, past the validity of free will, would be what's the fucking point? Even if I do possess free will, it doesn't change the fact that nothing matters and that their is no point. It just means that I'm responsible for what I do, but responsible to what or who? If its morally related to the other minds then there still remains no point, because when I cease to exist I won't be able to even care. Ultimately we are worthless and without purpose - that's what erks me most about my existence.

Way too easy.

1. Reality is what exists independently from any ideas about it. (Tautologically true)
2. If mind creates reality then it is not independent of the mind's ideas about it.

Therefore, mind does not create reality.

You use logic (which is created by the mind) to attempt to disprove my supposition that the mind creates reality. I know you're better than that, throw me something else. What you did would be like disproving the existence of God by using the example of the Holy Spirit.
