Negative Vibes

How can I clear the effects of being around negative people? It seems to really impact me.

Think of emotional frequencies as radio stations on a dial. It sounds like you just allow yourself to change stations. Don’t do that. 
I’m only half-kidding because I know how hard it can be. But it truly is an inside job. It’s all about managing your own frequency and energetic boundaries.
Remember, you don’t absorb the emotions of others, you match your frequency to theirs. You basically recreate those same negative emotions for yourself, then you feel bad too. Not helpful for anyone.
If you find yourself in a puddle after hanging out in a fear-based vibe, try any or all of these to clear and raise your frequency to love or above:
Breathe in and imagine your energy body expanding. 
Come back to the present moment. This will help to clear the emotions that you duplicated for yourself that have nothing to do with you.

Focus on your heart chakra and bring to mind something or someone you love and appreciate. You can do this anywhere, even when you’re in the thick of it.
Go outside. Take a walk and ground in nature if you can. As you ground, breathe deeply and as you exhale, imagine letting all of it fall away. Nature loves to recycle our messes. Remember to give gratitude and loving energy back.
I’m a huge fan of Epsom salt baths. They clear and reset the energy body.
If all else fails, watch Brian Regan’s Refrigerator Salesman stand-up bit on YouTube. This may actually be the most effective.
