Problem solving doesn't have to be just about current problems or problems as they occur. Where it's possible, you can also pre-empt and plan ahead for times of stress. Know what your stressors are, when they are going to occur, and prepare for them. Get yourself in good shape. Prevention is better than cure when it comes to stress, and it will always be harder to deal with the stress once it has happened.
For example, you know that your in-laws are going to be visiting on a certain weekend, and that this can create pressure and lead to stress. Think about this in terms of units of pressure, which we talked about earlier. It takes 50 units of pressure to make you stressed, and your in-laws on their own are worth 40 pressure units. You need to make sure that you are at no more than 10 pressure units when they arrive. Have a relaxing time the previous weekend, make sure you have everything prepared, and give some thought to particular things that they do or say that cause the pressure. Make sure that you are as relaxed and pressure free as possible when they arrive, and try to avoid whatever it is that usually makes their stay so stressful.
Stress is a medical condition and it can have a serious effect on your health. If you think you are suffering from stress it is crucial that you consult a medical professional.
