How Can Anxiety And Depression Be Treated?

My mom had a stroke over a year ago. She can no longer stand cannot feed herself as her hands don t have the coordination or strength to do so. She is bedridden, must be bathed, diapered, fed, etc. she gets extremely anxious, and constantly wants you to sit with her hold her hand, etc. she takes lorazepam, one used to help now two are just enough, temporarily. She is depressed and panicky. Is this typical. Can anything be done to improve things
