I am that friend....
Yes, my old friend Holly was a Debbie Downer. <br />
It sucked. After about a year, I just couldn't handle it anymore and we started to drift apart.
Yeah, didn't last very long. I found I started to distance myself more and more and eventually we just parted ways
I had a sister in law who was like that. Even when things were at their best in her life she was negative and down. I was pretty happy when she moved far away after she and my brother got divorced.
