You can try to switch up your controls and try and see if it helps or not, if it doesnt then just go back or change to something else (but not too much)
Im pretty sure i changed my keybinds like around 3-5 times ever, and some of the changes did help from time to time
Like what Catzer said, try playing lower diffs first and getting used to the lower diffs and move next to higher difficulties, you can try to play around with mods and such to make some lower diffs harder and such
You just need to play and practice mor, its sorta normal for one to not feel comfortable on playing harder diffs due to the lots of jumps and dashes
So its best to let your hand practice and get used to it first, so it wont feel awkward.
