If it was possible to dig a hole from the top of the earth to the bottom and jump straight through, would you come out on the other side, feet first? head first? or would you be stuck levitating in the middle? of course this is assuming there is no core and you could not be crushed by gravity and etc....

Yes, assuming that you would not be burned alive or crushed to death AND that this scenario were possible, you would be stuck, levitating at the center of the earth. In physics this formula (see below) states that the closer you get to the center of a large mass's core that stronger the force of gravity is:
g =[(G)(m1)(m2)]/r^2
from this we can assume that if you are at the center, you would stay there.

Assuming that all that you wrote is possible (and of course it is not, but no problem), and also assuming that the hole is just wide enough for you to go through without any tumbling motion (so your orientation stays the same), and assuming that there is no air friction (our list of assumptions is growing as long as that hole!), and assuming that (this is the last assumption, I promise) you jump in from a height of say 20 feet, you would come out feet first and reach a height of 20 feet above the ground level on the other side (Oh, sorry one more assumption and that is that the earth is a perfect sphere and so the surface the other side - not bottom or top is at the same distance from the centre of the earth). And you would fall back and come up the original side upto 20 feet head up! And this oscillation will go on for ever! If we introduce even a small amount of air friction or friction with the side walls (though we said the hole is big enough, somewhere you may feel like touching the walls), you will be slowed down and you may not exit the earth the other side! And finally you will be stuck at the centre of the earth. Rest in peace!

If you discount the rotation of the earth, you would travel all the way through to the same altitude that you jumped from (discounting air or any other friction) and keep modulating infinitely.
If air is in the hole, your velocity would be slowed by air friction, your modulation would decrease due to air friction and you would eventually stop in the center of the earth.
You would stop in the center due to equal and opposite gravitational forces exerted on you by the mass of the earth (relatively) above and below you.

You would undergo damped harmonic motion, that is you would go back and forth between the ends but the air resistance would make it so that at each crossing you are a lesser and lesser distance from the centre.

you basically favor new acquaintances that easily want to loaf round with you. As a social individual, like you suggested you've been, I doubt you want being a loner that a lot. in undemanding words an introvert and/or shy individual can develop right into a loner and easily savour it.
