If you know of a loved one who is sick, there are certain things you can do to help them. If they are in the hospital, you can visit them as much as possible to keep them company. If they are at home but unable to fully care for themselves, you can do whatever it takes to make them comfortable. You can prepare food, assist with finances, clean - ask them what they need. If the illness is sudden, you may have to cover for them and make calls to their place of employment as well as other family members. Go with your loved one to visit the doctor and be involved in their day to day lives.
Helping others definitely gives our lives purpose. It can be a rewarding process. This is particularly true when we are helping loved ones. We learn that there is a certain amount of give and take in every relationship. Of course, some loved ones might have a sense of pride that doesn't allow them to accept help very easily. Be sure to find out what works for them and what doesn't. Being sick isn't enjoyable at all. Feeling needy and dependent on others can be an unnerving experience.
Sometimes the only thing we can do to help loved ones is simply be a calming presence. Many times you can help them get better just by being there. Help them maintain low stress levels so that they can focus on recovery. This might mean doing their laundry, taking the car in for an oil change, or just sitting with them during their favorite television shows. The point is to provide a support system and let them know they are loved. That is often the best form of medicine.
