i have to agree with the others. play more. get better. try hidden later.
i've been in this game a long time and stuck around your skill level for a VERY long time. obviously also tried all kinds of mods. but hidden is really a mod that kinda combines with faster approach rates. you will see that hidden will, in later stages of the game, not nessercarily make the maps harder, but maybe even easier because the notes would usually appear very fast, so that you can't react in time. but hidden will kind of act as something, showing you the future. so instead of instantly reacting, you will be shown, how you are supposed to react in the upcoming time. this is why hidden + hardrock is a rather popular combination.
with lower approach rates the note appears and you just have soooo much time to hit it. you don't really know when you will have to hit it that well since there's a much larger gap between the notes appearance and the time you actually have to click it then with higher approach rates.
if you play hidden, like the other user suggested - just playing it with nomod and then with hidden - you will basically not play the song, but rather memorize what the map is like. bascially like a easier version of flashlight.
oh but the tip with the right skin is also pretty good. there are to many effects on the osu! standard skin. go try some skins of the pro players like rafis, cookiezi, etc. (i don't really recommend the one of hvick. just my opinion. it has some more 'visual distraction' then the others in my opinion). why? because in hidden you will come across notes that are overlapped for example. when you hit one note, there might be some particles and 100 signs and what not that will block your sight, and thus you might not see the note that was behind this note.
well. that are my tips. if you really want to play it, play it. you won't get worse. you probably won't get better. it might be fun. but if you want to have more fun with hidden get better overall and combine it with faster approach rates or play hidden + hardrock combined to enhance the maps approach rate.
