One of the weightiest issues of caring for a mentally ill spouse, child, or friend, is that it is so phenomenally relentless. The disease is so unpredictable, in its intensity and its spontaneity. You think you have the situation in hand, and it breaks out somewhere else, and often in public and causing major problems. This is wearing on anyone, including the Christian believer. And sometimes that can even make it more challenging.
You will need a support network, if you’re going to be a caregiver. This support is received in three different ways.
First, emotional support. Without someone who can listen and give words that encourage you, you’ll grow in resentment and frustration with your particular “lot”.
Second, I would suggest physical support. You will need someone to help you make sure the practical issues are met. (washing the car, fixing the shower, etc.) My wife as a caregiver has had to do things that she would normally wouldn’t be called on to do (fix the stove, do the taxes, etc.) because of my illness.
Third, spiritual support. It has three concentrations. Worship, prayer, and fellowship. These three have obvious effects on the caregiver. Just a word to the wise–when you pray you are going into it as two people (as well as for yourself). You must maintain and strengthen yourself and for the person you are serving. I think this is critical to your relationship. Try to see challenges, not obstacles. Don’t forget the power of a worshipping heart or the warmness of good Christian fellowship.
God gives special grace to the caretaker. My advice is to take it, and then use it. Draw upon Jesus who is your caregiver. Present your afflicted one to Him. Be supernatural in the mundane. The story of the paralyzed man on his cot being brought into Jesus’ presence by his friends fascinates me. It has many parallels for you to be a good caregiver.
“And behold, some men were bringing on a bed a man who was paralyzed, and they were seeking to bring him in and lay him before Jesus,”
Luke 5:18, ESV
My last word of advice is that you don’t be self-critical or feel guilty. Remember, it is your friend or family member who is the sick one. Don’t get consumed by your responsibilities. Don’t fall in the trap of judging yourself by how well you do or don’t do as a caregiver. Remember, you are not performing for others, but for an audience of One, who sees all.
