I don't think you can BE HAPPY about this condition in this ever-changing world that seems to spell out our certain demise, individually and wholly. We may actually cause a complete collapse of the eco system before the profiteers learn this lesson.
For me, I was already on a deeply spiritual path. I saw humanity was on the wrong track back in 1982 and began praying every waking moment for GOD to show me what to do with my life that would matter. I'm not a big fan of being on this planet as I haven't seen the best in people so I reasoned "If I HAVE TO be here, then let's make it matter that I came through this place". BOY DID THINGS TAKE OFF AFTER 6 YEARS OF ME BEGGING GOD!.
I became very ill while being a typical wife, mom and church congregant and the church teachings on health and healing failed as did the 11 doctors I saw in 18 months so I canceled all medical appts/tests and chased GOD down for answers. HE SHOWED UP and took me on quite a journey and then INSISTED I write a book. It took 21 years to finish. Providential events took place that ended up having a renowkned doctor introduce me and the book to the world and my cell phone blew up. I held it up to GOD and said "Uhmmmmmmm I don't know Your intention with this book/story but I DO NOT LIKE THIS. I can't think of anything worse than being an IN DEMAND author who has a cell phone." A year later I touched the screen of a newer iPhone and a pain shot up my arm that changed my life. THIS WAS NOT RANDOM...BUT PART OF MY PURPOSE. He leads me into amazing challenges but the book shows how He also leads me out of them.
So I guess the answer is to ACCEPT IT as part of your journey as there's not really anything other productive attitude. CONSIDER that some of us are the 10% weaker environmental messengers warning the able-bodied and DO YOUR BEST. My strong suggestion is to ASK GOD FOR HIS HELP as I have done, beginning 40 years ago, and then WATCH FOR HELP TO SHOW UP BUT BE PREPARED TO CARRY WATER OR PARTICIPATE. Nobody is likely going to COME SAVE YOU so you have to paddle and assume it's part of your spiritual training.
That's all I've got here.
