I am *always* feeling jealousy.
And since I learned to accept this about myself, I can deal with it much more easily. Sometimes it's just an annoyance I can swat away. Sometimes I need to give it more attention. Usually, just telling people that I'm feeling jealous is all I need. Give it a voice, acknowledge it, and it steps aside to let me on my way.
This is a MUCH better technique than my old way, of trying to stuff it down and silence it, which leads to it eating me up from the inside out.
