Caregiving while in assisted living?

My mother had a stroke 3 years ago and cannot live alone. She is at an assisted living facility although actually I think a nursing home is what is needed. I go to see her everyday and take care of her daily needs and supplies. Is this considered being a caregiver even if there are staff members who also take care of her? I feel very guilty a lot of the time because she is there and not living with me, but she is too handicapped for me to handle.

Thank you.
