Aura cleansing

Hi yall.. I feel like I need to cleanse my Aura. I feel as if I have a dark cloud hanging over me. Sometimes I feel like a shit person even tho I don't actually do horrible things, it's just a feeling I can't get rid of.

Anyhow,

Had anyone been through this and had a cleanse of some sort and don't mind sharing what they did ?

I know it may sound weird to some people..but thought I'd try my luck here

Thanks
