What do you mean “quality” of life? Since we are co-creators of every thing in our lives, our lives are in effect perfectly what we want. If you say you don’t like what you bring into your life, then it’s up to you to change it, by changing your beliefs. If you start saying to yourself, that your life is perfect, then you just might see changes happen that will verify that for you. Take a close look at all of your beliefs - you have many that don’t serve you. But they are in line with the events of your life. You might try to find a counsellor who can help you examine your belief system and help to identify ways to change it for the better. Quality of life is subjective. Some of the poorest people would tell you their lives are perfect because they don’t need anything more than they have. That’s a good starting point. Good Luck.
