Hi Brief background: 19 year old college female at UC Berkeley in California.
On Nov 30, 2011, I was drunk and fell off a ladder, 4 foot drop onto concrete. Hit the back of my head and luckily didn't get knocked unconscious but had an awful concussion nonetheless. 3 weeks later, I hit my head on a bedpost while cleaning my room. I developed awful PCS for the next 9 months. I could no longer exercise, focus on studying, do simple tasks, etc. All the typical symptoms of PCS. it was a nightmare. I also developed severe depression and anxiety. Honestly, I don't want to sound weak, but in March I considered suicide on a serious scale.

Long story short, after much rest, a year later, I am not 95% back to normal! The only thing I still have is floaters in my vision when looking at something in bright daylight, as well as headaches from vigorous exercise. But anyway, don't give up hope, it gets better!
