Why is it worse at night? Why is it ALWAYS worse at night? Is there some actual, biological reason why I can be having a normal, even good day, and then, like clockwork, I feel miserable every evening and go to bed fighting off the urge to cry? Then, when I wake up, I'm generally okay again. Is there a reason for this or am I just messed up and doomed to deal with depression as soon as the sun goes down. I feel like I'm two different people most of the time.

It's exhausting and I want to know why this is and what I can do to make it stop. I'm relaxed, I'm sleeping enough, I'm eating well, I'm getting exercise and sunlight and taking my meds and doing everything I'm supposed to, but EVERY NIGHT none of that seems to make a difference at all.
