for me it has been helpful to frame it as getting through heartbreak rather than over - i’ve felt it is more of a journey rather than having an identifiable threshold or fixed point of being “over” the person. so - these are my main recommendations for things to do to get through the heartbreak:
this isn’t true for everyone, but for me and most people i know, one of the worst things for processing is being around the person a bit right after—it‘s like making your emotional process and brain not be on the same page—so space is probably the #1 thing i recommend as being useful to fully processing that you’re not together romantically.
music (also films/shows too) can help you feel seen and understood—heartbreak is a unique type of hurt. i have like 3-4 playlists from different heartbreaks i have been thru lol!
journaling, to process your emotions solo, though sometimes adding a therapist is needed!
hobbies (solo or with friends) so you can find ways to do positive & engaging things in your increased spare time! spend some extra time being in love with yourself. ❤️🩹
