I'm a nurse (an LPN/LVN). I do private duty nursing, so I only take care of one patient in their home. It works for me because it's low stress (usually), I don't have to deal with any coworkers except for the RN case manager that comes out once a month to update the care plan, and I only have one patient to care for. The only downside is the pay.
As far as getting your license reinstated, you'd have to contact your state board of nursing. Are you RN or an LPN?
