Why can’t I control my emotions?

For the past three years, I’ve been suffering from depression and anxiety. What started out as simply academic stress became countless nervous breakdowns and panic attacks. It feels like a never-ending ride. I no longer recall what it feels like to be “normal”. I’ve shunned many people away from me and lost many opportunities. Why can’t I control my emotions? I wonder. 

“The greatest battles we fight, are the ones with ourselves.” It truly is isn’t it? I am fighting against the depression, against the anxiety within me, and although I haven’t won yet, I know I will someday.
