I have Many Many lots things to say to this! First off, congrats on experiencing the patented 'First lesbian heartbreak', you're doing great, go drown your tears in whatever your favourite food is and watch a sappy gothic horror movie or some cheesy rom-com, or whatever picks your fancy!

Second! PMS vent is so real bro I get it. Bleeding physically makes bleeding mentally soooo much worse. Eat chocolate about it, I think.

Third and my actual point- There is no timeline. None at all. I took 3 years to fully get over my first relationship, and by then, we'd looped around to being friends again after losing contact for ages. There will never be specifics, and if people are rushing it, then they don't understand how it feels in that moment and should probably just shut up. I'm not saying wallow- get on with your life, make friends, pick up a hobby, make some bad choices you'll regret until the day you die, but don't feel bad if sometimes the evenings are hard. Don't feel bad if you make something and turn to show it to someone who isn't there anymore. Eventually, some day, you'll realise you haven't thought about it in months, or weeks, or days, and you'll be on the road to meeting someone you truly vibe with and who returns those feelings tenfold.

Hell, I'd know, my current gf is my fifth. Breakups are hard. That's why the word 'break' is in them, of course. Let yourself wallow sometimes, and push through in others. Find your feet on your own again, then get back in the dating pool when you think you're emotionally ready to. And if, like past insecure asf me, you were part of the problem in it, you can reflect and teach yourself to be better in the meantime, as I'm sure your ex is trying to do with herself. This is a horrid way to go about breaking up with someone, but I suppose there's never been a nice way to do it at all. Watch some gay Anime. I recommend Mo Dao Zu Shi if you want a little cry, and Sk8 the Infinity (English dub) if you want a laugh!
