How to stop being sad about still being single?

I'm 27 now and now I see most of the people I know younger than me getting married and most of my friends married now. Its hard especially at my church where after service I see women going home to their husbands or leaving happily with their boyfriends to go on dates. And I just go home without a spouse. It just makes me want to cry and eat chocolate all day but that will just make me fat lol
