Conquering my fear of heights! Searching for hikes with ledges, drop-offs, cliffs, ...

Calling fellow Seattle area hikers! I am doing exposure therapy to conquer my fear of heights (specifically edges) and need some hikes that fit the following criteria:

-Day trip from Seattle -open in spring (I need to work on this now) -Under 6 miles, non-technical, not actually dangerous -Hike includes steep drop-offs, cliffs, ridgelines, scree fields, narrow trails, exposed views, lookout towers, etc. -no crowds! (I will distract myself by yapping with fellow hikers and that does not help with therapy)

Please let me know if you have suggestions! These don't need to be terrifying or technical - I'm no thrill seeker, just looking to push my boundaries of what is comfortable.

Some hikes I have struggled with: Grasshopper Pass / Tatie Peak, the last little climb for Yellow Aster Butte, the scree field return from Burroughs, Klahane Ridge, Sauk Mountain, Ptarmigan Ridge. I just need some spring options!!

Thanks all!
