I know this is ridiculous! I'm early 30s, fiancé just turned 40, getting married - I feel jealous of people getting married in their 20s with decades of youth with their spouse to look forward to. I feel like I don't have that and although I am excited for the wedding and to be married I feel a bit like there's not much after that to look forward to, like its all downhill? I'm being ridiculous aren't I? Why can't I shake this feeling?
