Is it Jealously, Intimidation, or Fear of Self-Reflection

The stem of jealousy and intimidation is ignorance or rather simply explained by the fear of self-reflection. As I approach this topic I must trend with caution to avoid the tone of self-righteousness or lack of sympathy towards any who might struggle with this. In all of our lives, we have reached a place where we have felt less-than or not as valuable in the sense of personhood but what perplexes me is the reaction to others on the premise of how you feel within. For example, suppose I was feeling ugly in yellow pants but then I have a roommate who looks great in yellow pants. Being insecure within myself I then proceed to demote how she looks in her yellow pants in order to achieve an imaginary "beneath" level I want to place her due to how I was feeling within. Unknowingly, I placed my insecurity on another without their knowledge. 

Some questions I have to the Lord on this topic:

Supposing I was the unaware roommate how do I protect myself from that type of unassuming attack?

If one were aware of this attack how would one address this in a way that is Godly and of good approach?

I know you may be wondering what this topic means for me or how this is even important but I have been noticing a pattern in all of us. We place our feelings of lack-ness on others and try to boost ourselves through materials, activities, or anything we feel that can allow us to one-up others. The reality is whenever you feel like you are lacking within yourself whatever that lack-ness may be... you are... because the way to fill the lack in your life is to fill it with the presence of Yahweh. Whenever someone is intimidated by you remember the said someone is not necessarily threatened by you it is the problem within themselves reflecting on you, trust Elohim to deal with the problems you can't see.

What I am not able to handle, God is capable to deal with
