You are in a hard position...do you have any other family members that you could talk to? In our area there are support groups for caregivers....it is something that you could look into as well. Talk to your doctor and he/she should know what is available in your area. You will meet with others in the same or similar situation as you are in. Being a caregiver is mentally and physically demanding and your health is more important.
Remember to take care of yourself too.
