Pen isn't working properly

So the problem is like, whenever my pen gets close to the monitor it would click without physically touching the tablet. The cursor will dissapear whenever it gets close and I can only move google like scrolling down and when im at my drawing app it won't click anything. I'm a kiddo so I really don't know how to solve this. I've been researching stuff and did almost everything I read like restarting my computer, reinstalling the driver and even replacing the nib but nothing worked so please help me out here.
