Do you know what, it's natural to initially feel a burst of 'How I wish that were me...' however how you progress from that is completely down to you.
The way I deal with life in general is that anothers good fortune is never going to effect the bounties Allah has stored for you.
I always always make dua for my loved ones first and ask for them whatever I want for myself before me, their good fortune is not going to diminish Allahs bounties to me and I love to see my loved ones happy and content and enjoying the bounties of Allah. Sharing in the happiness of others brings its own barakah.
Make your heart bigger, Allahs bounties are not so limited that they will run out before they get to you, your acknowledgement and happiness for others will increase your own share, you'll see inshallah.
