I want to second what Sue suggested about hospice. I helped both my mother-in-law and a close friend when they were in hospice and they got a lot of support and pain control. With hospice, you never have to go to the ER again. They can support you in dying but also can help you live in a much better manner and often even live longer. If hospice isn't right for you, do consider. Palliative Care which should give you pain control, access to visiting nurses and more. Were either hospice or palliative care suggested at the time of discharge? We can make choices for ourselves but it can take some planning. Do you have a primary family member or friend you can sit down with and discuss options? I was in the ICU for months as a very young woman and I saw that white light tunnel too! I don't know what it means, but the whole NDI certainly has informed my life for the last 50 years. Hoping you get the support you need.
