Here are a few tips:
Tell your loved ones how much you love them. Tell your parents, spouse and children. Do it on a regular basis.
Be grateful for what you have. You will feel so much better if you are contempt. Everyone has something to be grateful for. Think about it. Try to be forgiving and give the benefit of the doubt. Even if you feel you are right, its just not worth it, to hold it in-for your health's sake.
