I know this song is probably way too hard for you but i think this is one of the best "hard" songs out there that feels good to pass
https://osu.ppy.sh/s/24313This is the current song that i would like to pass but there that one line jump that goes back and forth that i can't do ;-;. This song has really low hp but its insanely fast (for me) which is why i think its a good song to try to pass. When your feeling good and you miss a circle and just fail makes ya feel real bad yaknow? But with this song if you can miss circles and if you regain your cursor movement maybe even after 5 misses you can get back in
And after you pass it you can disregard the fact that it was hp3 and feel like a god bc you passed a 7 star song HAHA. So ya this should definitely be one of future milestone maps :^)
Anyhow, as for possible milestone map recs for you currently, based off your top sscore i assume you play low 4*? If so the classic dear you
https://osu.ppy.sh/b/136400&m=0 is pretty good imo . Its got long streams but they arent too fast. Has like 3-5 long streams so you gotta have a little more than just luck to get through them C: Id say take what you lack at (streams or jumps) and make a map that is .5-1* above your casual level of olay that specializes in that area and make it your mile stone. If you want any more recommendations just ask (づ。◕‿‿◕。)づ
P.S I believe that the great wall of text is an amazing wall
