I'm widowed recently. I really really need free adult diapers.

Please speak to your MD's office about resources for incontinence wear. I honestly don't know where else to direct you.

Where I live we have in home services with Hospice. Call and see if they have been donated diapers. Are you on Medicaid? They have an allowance for diapers. I worked for Visiting Nurses and we were donated diapers all the time. And as said Food Banks.

Call your local food shelf and ask if they have any.
Sometimes thrift stores get them, and they are not always put out. Good Luck

I know that the local food/clothing and financial ministry that I volunteer for always has a plethora of adult diapers, so please call around to your local ministries.

Where are you located??

Check to see if you have a local diaper bank.

There is a Facebook group called the Buy Nothing Project You sign up for it by the area you live in. I know on ours, I often see people giving away diapers (often unfortunately as a person died, doesnt need them anymore, or in the case of kids diapers they grew out of them.) You can even do a search it to find them.

If you sign up there, it will put you in a group based on your locality.
