I feel guilty after reading this, haha. Like you said, every body has a negative side and sometimes we tend to ignore or hide this side of ourselves.
I've had mine too, mine had been more of low self esteem, thinking I wasn't ever going to be good enough, thinking I wasn't worth anything. That negativity lived with me for a while and I missed a lot of opportunities.
They're a lot more that I tend to get rid of and hopefully I will, with time.
Thank you for making this post
