Spin off from the what makes you green thread.
How do you handle your jealousy? Do you project it onto other people? Does it turn you into someone completely different?
Going by that thread, a lot of people mentioned things that describe me, and I have lost friends over some of those mentioned things. I have lost even family due to some of those things mentioned.
I think jealousy can be/is a very dangerous and horrible emotion, and having been on the receiving end of jealousy I try to deal with my jealousy as MY issue. Mostly I am not a jealous person, and if I feel jealous I work through WHY I feel jealous so that I don't project it onto others who don't deserve it.
I have had to hold back a lot of information about myself, or downplay a lot about myself, because I'm scared of being hurt by people when it doesn't matter to me how much a person earns, what they own and where/how they live. I just don't judge my friends and family like that, I value them for the people they are.
