How to get over a triad breakup

I (22F) got recently broken up with by my now ex bf Cedar (27NB) and gf (26F) Apple after just over a year together. This was my first relationship ever. They’re an established couple and already had future plans together, while I didn’t.

Me and Cedar broke up due to incompatibility in the long run, and full of insecurities, it was a more hurtful breakup. While me n Apple’s break up was bitter sweet as we didn’t have any issues. Our last hug was 20 minutes long. I told her I hope my next partner is a similar to her. And we promised to be friends after healing. I think if I only dated her it would’ve been polysaturated as the two of them live together already. We never got to celebrate our 1 year anniversary as we fell out a day before it.

There’s more to it but that’s the gist.

I’ve been ok for one moment and on the brink of tears the next. I’ve been crying in my car after work because I’d usually text them by then, they were a part of my world and routine. Last night I openly wailed mourning the relationship, good thing my parents weren’t home. I never cried over anyone this much, dead or alive, ever. My parents have been noticing my withdrawal, spaciness, and lack of appetite. I’m just in a state of shock almost thinking “did that really happen?”

I don’t know when I’ll be ok. How do I move on?
