What is your experience with running?

I started running some months ago, during summer.
I did it atleast twice every week, it was addicting. 
I felt so good during that period, no depression, I wasn't happy but I had a costant good feeling in the background. I kept running during Autumn , even if I didn't get as much sunlight and it was starting to get cold I kept going and kept feeling good.
Then I skipped a day, which turned into a week, now I haven't ran for a month and I feel miserable, I keep saying that I will run later, or tomorrow...
Looks like the cure for my depression will be to run away from it everyday, and the snowball effect goes both ways, I am feeling so much resistance right now to just put my shoes on and go run in the cold, and when I used to run every week it was way easier... fuck it I'll do it now, hope to come back and read your experiences
