Length contraction v nature.?

It is confusing ...

but a word comes to mind :

Relativity.

Someone on earth observing you approach at near light speed, would see you shortened in the direction of travel, you clock will be all but stopped and your mass will be nearly infinite ...

But you will perceive your time passing at normal speed, and your mass and size will be normal.

But you will also perceive yourself at rest and you will see the earth rushing toward you, clocks on earth will be stopped, and the mass of earth will be near infinite.

That is relativity --- Einstein understands it better than I do. But he's keeping mum.

In physics, length contraction – according to Hendrik Lorentz – is the physical phenomenon of a decrease in length detected by an observer of objects that travel at any non-zero velocity relative to that observer. This contraction (more formally called Lorentz contraction or Lorentz–FitzGerald contraction) is usually only noticeable at a substantial fraction of the speed of light; the contraction is only in the direction parallel to the direction in which the observed body is travelling. This effect is negligible at everyday speeds, and can be ignored for all regular purposes. Only at greater speeds does it become important. At a speed of 13,400,000 m/s (30 million mph, 0.0447c), the length is 99.9% of the length at rest; at a speed of 42,300,000 m/s (95 million mph, 0.141c), the length is still 99%. As the magnitude of the velocity approaches the speed of light, the effect becomes dominant, as can be seen from the formula:

I am not sure what you are talking about. The flattening of an object that moves near the speed of light (either your speed, or its speed, doesn't matter) is simply an optical illusion due to time dilation, isn't it?

Say you travel at a near speed of the light and you switch your headlight. It will illuminate nearly instantly any object ahead of you. But from my frame of reference, say on earth, I will see your headlights moving slowly ahead of you because - from my frame of reference - nothing can move faster than the speed of light. Hence we observe two different things as good old Einstein told us.

Objects aren't really "flatten out" and it doesn't change their masses or radii. ... or did I misunderstand your question?

Your question is in error

If you are traveling close to c, you will observe Earth foreshortened in the direction of travel (it's radius in the direction of travel will be shortened) and the mass to increase towards infinity (and the time to decrease to 0)
