Putting pressure on right side of trackpad makes the button not work properly

[azndude160]

When I'm sitting down and using my black macbook, I usually put my palms down on the macbook. But when I put my palms down when using the macbook, it puts pressure on it. And when I put pressure on the right side of the trackpad, it has the same effect as if I'm clicking using the trackpad button. Does anybody know why this is? It gets very annoying because whenever I'm typing and I have to move the cursor away, it usually highlights whatever I typed and when I go back to typing erases what I wrote since it's highlighted. This is because of the pressure put onto the right side of the trackpad. Also my battery kind of sticks out on the right side, and when I push the part that sticks out, it does the same thing, as if I'm clicking the trackpad button. Only way I've been able to avoid this is by lifting my palms up while using my macbook or connecting a mouse, in which case I find both as annoying and bothersome. Is there anything wrong with my macbook??
