I have never really suffered from writer's block. I tend to have too many ideas for stories! What can be difficult is sorting through all the ideas and deciding which one to dive into first.
On to writer's block==
1. You can try meditation. If you're super busy and stressed you can try to slow down for a few minutes each day and focus.
2. Exercise and get your blood pumping!
3. Go for an outing. Getting around people can sometimes kick start the idea box.
I use these same strategies to help streamline my thinking. Good Luck~Min G
