So sorry for that.
If she is that important to you and still alive, just have faith that she will eventually come back. You can ask that the Will of GOD be done concerning this in prayers. Sometimes things like that could happen for good reasons which is GOD's Will but if it's not GOD's Will and you live according to HIS Will, HE will bring it back.
I believe we could easily get HIS attention in humility and sobriety even when we are lost and far away from HIM. Just talk to HIM about it always in that state of mind.
Hope she is OK. You could still get yourself another nice one if need be.
I am in no rush in getting another one or replacing her. We have other felines in the house, but she is still the one that I loved the most and my favorite of them all. I am still having high hopes that she is okay and come home safely. Still my heart is aching, I cannot stop imagining her while I am working, sleeping and doing other things.
I’ve decided to look for her in the early morning within the neighborhood in a certain radius. There are some who are almost similar as her but not that close (especially the one I saw in a gate where it’s under quarantine). I’ve made a few rounds until I’m tired of looking and taking a break.
I know that she’s not far away. Either she is hiding somewhere (because of the rainy season) or she was attracted by another cat outside. Maybe she would get pregnant later on.
