How to deal with jealousy

I understand that jealousy is a feeling created by a thought and that I should focus on what I am missing in my own life. But when you are jealous that people are traveling and you are not able to right now, how do you cope at this moment with the feeling?

I am having a hard time with family members right now because no one is calling to see how we are doing, they just text photos about their vacation home and vacations they have traveled extensively for the last year. It comes across to me as being excessive and bragging. I personally would tone it down right now especially with many people going through a pretty difficult time in the world.
