I was harassed and I quit! Now can I sue—Or get unemployment?

Q. I found my working conditions to be intolerable because of the behavior of my male co-workers that I considered to be sexual harassing. I just did not have the energy to complain about the behavior and face the consequences, so I quit without telling my employer about the harassment. I am having trouble finding a new job, and now I am thinking I made a mistake. Will I be able to sue my employer for sexual harassment? Can I obtain unemployment insurance?
