STOP FREEZING!!!!

WTF? I'm getting so frustrated with my Mac. It's so stupid!!!! It keeps freezing on me today after I updated all of the software! It took forever to update the software and I was tired, so I charged my laptop while I was sleeping. When I woken up, it was finally done. Now, my battery is dying fast. It was just 100 percent now its 98? WTH? I think I over charged it and the battery sucks now. UGHHh! Well, good thing I bought insurance. Wow its 97 percent now! I been on my laptop for 5 mins at least.
