My cat has been missing for 2 months

Hello everyone, I don't post much so im not sure where to post but i saw lots of other similar stories on this thread and wanted to share my story. I moved across the country with my cat in March this year and my sweet tabby went missing in May. She snuck out when a family member left the front door open for too long. We didn't realize she got out until the next afternoon when her breakfast was left untouched. We did everything from canvasing our street, posting on all social media, printing flyers, knocking on every door in the neighborhood, leaving mini flyers at every door in a two block radius, and not one person has seen her. She's microchipped and registered so if she was found and turned in somewhere I would've been notified. I was, and still am, absolutely devastated and heartbroken. She was my first cat, my emotional support animal and my best friend. She got me through so many life changes and was my whole world. Im in therapy, I journal, I meditate and I still have my moments of intense grief where I feel like I just lost her today. Ive read so many stories of people reuniting with their lost pets after way longer time periods and they give me hope. My question is, how do you deal with life while this massive piece of your life/heart is missing? How do you keep your hope of reuniting alive after all this time has passed? I appreciate any insight or advice, thank you.
