Oh Maw,
I'm so sorry for what you're going through. My own DH is going through many health issues and I often ask myself ' how will I face the world on my own without my DH....the love of my life and the one person who always has my back?'
So, coming from me, the person who's never been there (and possibly has no clue) I can only say this:
From your charmingly witty, entertaining, wise posts, you already seem to have the tools you need at your disposal. Perhaps you've lost a little bit of courage. There is no shame in letting your guard down now and then or to put yourself out there, especially when you expect the worst. Lower your expectations and who knows? You may be pleasantly disappointed!
We Humans have a built in resilience that somehow gets us through the worst in life. You are still reeling from your loss however, and even the most resilient among us must often struggle to find a way forward.
So, here's to time....and may it heal your insecurities and help you find what you need to prevail in life.
Hugs, Willa
