Ah op it's shite isn't it, I had to start my life over after the devastation of a cheating ex.
Yes, you're still young, you have time, but I would say try to take a little of that time to heal, take care of yourself and re-find yourself?
I had no idea who I was after everything fell apart, and I knew personally I needed to figure it out before I was in a position to start dating etc.
In regards to the fertility thing, you do have options if you did feel like that was something you wanted to look into - I've no experience with your specific condition but hoping some one might be along with better more specific advice on that one.
You might also perhaps need to work through your feelings in relation to the mc you've been through, there's a few supportive threads on that board on mn, a port in a storm ime.
If you have friends or family irl who could support you to re-group, maybe reach out to them? I didn't at that time, but slowly built a network little by little.
Wishing you well xx
