Hello so coz of the scarcity of space, I have the area seen in the red box to use my mouse (the mouse is sideways for viewers' reference and I am using a laptop table).

I currently play on 3200 dpi with around 0.121 sensitivity but it still feels like it is not enough and I have to lift my mouse a lot. Due to this, I have a poor aim too but I can't do anything as of now to increase my mouse area.

I tried a few aim training tutorials but I stuck at the point of bad aim coz I don't have much area to move my mouse around and if keep my sensitivity too high, I can't aim properly

So, any suggestions you guys have to use my mouse properly in this little area?
