I take care of my mother (92). I'm very sick. Have vestibular migraines I get very dizzy and fall sometimes . I know the owner of one agency I trust her. How can I trust the caregiver . If I fall asleep worried since I"m sick about a caregiver taking something .
Then, I'd address your own health. It sounds like you may need some medical help for yourself. Have you explored why you are falling and feeling dizzy. That would concern me.
If you are worried about things missing from your Mother's house, I suggest when you feel better to put those things into a locked room or if the items are small into a locked trunk.
