What can I do to avoid letting my jealousy ruin my enjoyment of my friends this summer?

My friends are coming home for the summer from their first year of college in about a week. I have spent what should have been my first year of college having surgery.
Needless to say, I’m a little jealous of the fun and new experiences my friends have had while I’ve been laid up. I’m excited to see people I care about after so long, but I’m worried that hearing about all the exciting new things they’ve done and learned is going to make the (perceived) unfairness of my situation just hurt like the dickens.
It’s not my friends’ fault that I haven’t gotten to have fun while they have. I don’t want to ask them not to talk about their experiences because obviously going to college has made a big impact on them and is part of who they are, now. I don’t want to make them feel like they have to walk on eggshells around me, but I’m still kind of in the “why me” stage of grieving and it all seems so unfair.
What advice can you offer? Thanks.
