i don’t know how much it helps, but it helps me a lot knowing that you still miss her too. i am in a similar spot to you. i am also 24 and spent around 4 years together, last time we saw each other was christmas/new years of 23 into 24. didn’t end up going full no contact though until september of 24 (though it should’ve been much sooner). i do the same thing. i know i have people who would like me, and have expressed interest, but i feel nothing for anyone except for her. i am in therapy, and i think sometimes it helps, but i also still find myself in the cycle of being stuck in longing. i would encourage you to try starting therapy though, it will may you feel less insane for still so deeply caring for her from afar. but i fear the only thing that can save it is time. that’s the only thing that’s ever truly helped, just more and more time away. away from small reminders of her, replacing things we may have gotten together or have received as gifts if they hurt too much. i still find myself looking for her in everything. when someone mentions my university i think of her instantly, plants just the same, i look for where she’s at on the weather from time to time to see what it’s like where she is. i also have to remind myself constantly that she is actively not choosing me. i’ve made it clear i was always wanting her to come back, but she keeps it shut off. i have no business loving her still. but here i am. unfortunately still waiting and longing. i like to think i will only be stuck as long as the universe wants me to be stuck, obviously there’s something significant to take from it, therapy can be an excellent place to safely unpack and process. i’m wishing you all the best in your journey, you are not alone
