Little story here. Today my mom woke me saying that she was going to a doctor, and needed me to take care of the house. My (step)father is out of the town until the weekend, working. After she left the house, I layed on the couch in pure silence, and... the first thought that came to my mind was "This would be the perfect time to kill myself". I didn't tried anything, because I really didn't knew any method that I could do (thanks heavens). The point is: I'm not depressed now. Actually, haven't been for a few days. But suicide came to my mind anyway, and if I had the means I would have done it. Is there any reason for this? Any explanation? I'm confused.
