i'll try and describe things as clearly as i can

i was originally on mouse the first year i started osu then i switched to tablet but switched back because the tablet was my brother's and he took it back around the start of the year or so

i stopped playing after 3 days of mouse because it was too uncomfortable for me after tablet
i would occasionally start the game and play only one map and leave because again, it felt miserable
now, something like 2-3 months ago, i picked up the game again and actually wanted to try and get back into it with mouse, knowing that i actually wasn't that bad with it before tablet

when i started, it felt just as uncomfortable as it always had, but i kept trying. i was playing regularly but not too much, didnt play things too hard nor too easy
i tried to hold my mouse different ways or position my arm or my body's while i was playing, but nothing came out of any of it and i never found anything i tried comfortable or benefiting my gameplay in anyway

at last i just picked the least problematic grip, sens and position
i can still play everything up until 7 stars or so, but not as well as i used to either on tablet or on mouse before i switched to tab

though my mouse and my mousepad are clean, when i play it always feels like something's sticking, and it makes aiming precisely harder, sometimes it prevents me from accessing some parts of the screen like the corners

when i play, i somehow push my mouse with my palm, which rotates it, but my hand doesn't follow the rotation, so it leaves me in a position where my mouse faces sideways, but my hand faces my screen
either that, or my wrist along with my arm slightly turn right but keeps my hand and mouse straight

i hope to get some advice i still didn't come across yet, because right now i dont really know how much more i can do if i wanna improve on mouse before i get a tablet, if i ever get one
