3 week stall

I fell on a three week stall where I have fluctuated a pound. This is my third month on 10 and I start 12 in two weeks. The stall is very unmotivating. I have been working out and I have been eating relatively clean. I did lose my grandma two days ago and before that she was on life-support for three weeks so I do recognize that I had a lot of stress. However, I felt like my eating habits were normal. Has anyone else ever had a three week long stall? How were you able to break it?
