It's very common to be depressed during the winter months, and especially around the holidays, when the stress is multiplied exponentially and loneliness is emphasized. I think everyone feels it, to a degree.
I've suffered from depression my whole life, one moment I'm happy then something small happens and suddenly I'm ready to jump off a cliff or I can't stop crying. Most of the time its just me lying in bed staring at a wall. It's gotten better since I started taking pills for it. But somedays it still hits. I've been suffering with it since I was like 5 years old.
Yeah. It's the holiday season, and I've lost my aunt and two dogs within a 36-hour time frame just last month. I've just found myself a distraction, something constructive to do to take my mind off of things. While it doesn't erase what happened, it helps anyway.
