You might benefit from an intensive writers workshop. Here's a good one:
The 4th Annual Seascape "Escape to Write" Retreat

WHAT: Tune out distractions and devote a weekend to reinvigorating your creativity and revising your manuscript in the beautiful Connecticut river valley
FOR: Writers working on mystery, thriller, or suspense novels or short stories for YA or adult readers
WHEN: Beginning at about 5 PM, Friday, September 9; ending at 1 PM, Sunday September 11
WHERE: Guest House Retreat Center, Chester, CT
