It doesn't matter if the whole world seems charged with negative energy. Chances are this is only an illusion caused by some unresolved conflict within you. Let go of that problem and it will cease to give out the negative vibrations that are clouding your vision. If the negativity is external, it may still be localized so you can easily move away from it. Or you may choose to remain and overpower negativity by casting your own penetrating illumination into the darkness. With practice, you can create a zone of clean, positive energy around you at all times, so that you always exist in that environment and serve as a beacon to others. However you choose to deal with negative energies, remember that reality is the Self, the Self is God, and God is Love.
