error in editor camera clipping?

Whenever I'm in editor mode, or on the "scene" tab editing the 3D game, moving assets, sizing them and etc, there seems to be a camera glitch. Whenever I come close to any of my assets or 3D models' surfaces, the camera "slices" them, and "cuts" pieces off. I'm not sure how to describe it other than that my camera is "clipping" with them.

Instead of the camera getting close to assets I want to be close to, the camera seems to delete them, or make them transparent.

it's like a clipping plane, but instead of being to far I'm too close.

please help! I'm a rookie and I'm assuming this has an easy fix, I just have to figure out how to fix it.
