Thank you for being so honest and self-aware. I think many people can relate to feeling emotionally and mentally drained after giving so much of themselves.This is probably a big reason as to why I'm not married.
It takes a very special person to think, "How can I serve 24/7?" -- and then actually hold up to the deal -- especially when an entire family is involved. And not just one's spouse and immediate family, but the two or more families (if step-families are involved, etc.) that marriage will connect them too.
I've found in my single life is that I have a hard time maintaining an even keel -- meaning, I seem to serve best when I can do so in a few very big shots. I save up all my energy and then expend it all to lead up to and and get through big events for set amounts of time (if possible.)
I go until I'm completely wiped out, then have to withdraw, and allow God to fill my tank to do it all over again.
Of course, many things in life can't be handled this way. Work of course, is very different -- but that's one reason I fought to work night shifts at one time -- so I'd be around less people, which is less draining and easier for me to be more steady.
I'm like this with friends and family as well. I can serve to exhaustion, but once that point comes, I have to completely withdraw or my "crazy" lets loose (extreme anxiety and irritation,) and no good comes from that.
I can't see myself in a situation where I have to serve nonstop 24/7 -- but if I may say, and looking at the divorce rate even among Christians, I don't think many other people are doing very well at doing this realistically either.
We all know how things "should" be, what we "should" do, and how we "should" think according to God's commands.
But no one can actually implement them as they were meant to be, so I often wonder how we can all get by (and still serve others) on the very little we try to do in comparison.
One thought came to mind as I was reading your comment. Marriage isn't about one person serving the other 24/7 without ever receiving anything in return. At its best, it's two imperfect people serving, encouraging, and carrying one another.
There will be seasons when one spouse is stronger and gives more, and other seasons when the roles are reversed.
I also don't think God expects us to live the Christian life by our own strength. If He did, we would all fail. That's why His grace and the work of the Holy Spirit are so essential. We don't become faithful spouses because we're naturally strong enough, but because God continues to shape us over time.
The fact that you're aware of your limitations is actually a strength. Self-awareness allows us to depend more on God instead of pretending we can do everything ourselves.
None of us loves perfectly, but by God's grace we can keep growing in love, patience, and self-sacrifice
