In general, single women (including divorced and widowed women) may not immerse in the mikvah. However, some communities do permit immersion on erev Yom Kippur (possibly erev Rosh Hashanah as well) as an act of
spiritual cleansing. You can check with your local mikvah, or with a friend or mentor, to find out if this is possible in your community. We hope you will be able to take advantage of this upcoming opportunity to experience immersion the mikvah.

We wish you much hatzlacha!
