OP, I can definitely understand how you feel.
OFten times, I wonder how those who are married for x number of decades, and far removed from the dating process and difficulties us single people face these days, can provide any true insight into waiting and dealing with singleness. It always leaves me scratching my head.
But on the flip side of this, there are some famous Christians (eg Michelle McKinney Hammond) who are happily single and write about how and why Christians who are single should be happy that this is their state. When I hear people like these talk, I still scratch my head, wondering how any of them can provide advice when they themselves are in a perpetual state of singleness (whether this be voluntary vs. involuntary is always unclear).
At the end of the day, I realize that I can and have become easily dependent upon what people are saying about my life as a single woman. It's dangerous territory. I'm working on just avoiding these types of discussions altogether, and rather turn my focus, my eyes, on the Cross. Each state that we exist in, whether it be single or married, married w/o kids vs. married w/kids, young vs. old, unemployed vs. employed, etc, requires a different form of sacrifice and refocusing on the Lord and His plan for our lives.
There is no one more qualified to tell me what to do with my time, my focus, my ministry, and my singleness, than Christ, Himself.
