I think it's helpful to remember that we all have a dark & light side. All of us - from the Dalai Lama to Ivan Milat. We all have it. How we choose to function with that darkness is what sets us aside.

Jealousy is something I think all human Beings have felt - even animals feel it. It stems from believing that someone has what you cannot yourself manifest.

Most of us can reason that quite quickly & turn envy into happiness for the other. Others take a bit of time to reflect. Some don't & it festers into the bitterness that is jealousy.

What I've learned in life is that it's what YOU do that's important. How you deal with that feeling being projected at you.

You have worked hard. You deserve whatever happiness & material things you have. This is not your problem. Don't however focus on her problem. Reflect on other areas of your life that you might need to work on (we all have them - my list is loooooong!). Take the lesson she is giving you. The lesson that we all have a dark side - hers is clear. Now look for yours and shed some light on it.
