You and Neptune have been on my heart so much.
We all keep saying, "Don't give up!" And, we mean it.
BUT ALSO. Know that you have done so so much.
DoN't give up - Until, or Unless, You are Ready to.
I am still praying and hoping so much he comes home to you. And maybe he will! Maybe you find him, maybe tomorrow or the next day, or day after!
But IF IF you come to the point where You feel Ready to stop looking -- or even to take a break from searching-- then it will be the right time to do so.
I encourage you to continue searching -- as Long as You still feel willing to do so. But IF IF he has not returned (and I am praying he does!) and you reach the point of need-to-stop, or even just ready-to-stop -- then Do So. IF IF you get to that point, you will be full of sorrow I know - and I know you are full of sorrow now also - but, tell Guilt to Shut-UP. You have done - and currently are doing - SO MUCH. And even though guilt and self-blame wants to creep-in (or come barrelling-in!), that's the one emotion that is Not valid. You need to know that.
I am continuing to pray for you, and for Neptune, and for all your birds.
