I have met many people who appear not to have problems if you only know them superficially. However, many people like this will come to me for psychotherapy because they often appear to ¨have it made¨ yet deep down they often come to a point in their life when they are not happy.
Other people may be truly happy for a decent stretch of time in their lives, but be assured, problems will befall everyone in this world. If you love and are loved, you will either grieve the loss of others or die quite young. If you do not love and are not loved, you will be miserable. At one point in my career, I worked with dying people and their families. Many of the people I met were very functional and had gone years without too many problems in their lives, but they too eventually encountered some problems and the pain of grief.
And those women who appear to have it made, who have security from depending on their successful husband, usually have to develop some strong defense mechanisms if they live dependent on their man, because they know that he could die. And in reality, often these marriages are not so good as they look. Often these marriages look good on the outside but last because of dependence, not happiness. (Be aware you might not be in the same position as I am to see the secret inner lives of functional looking people.)
Some people do have more problems than others, but do not be fooled into thinking there are people who have no problems. You are making the mistake of comparing how they look on the outside with how you feel in the inside.
I've met these kind of people,too. They seems to be problem less. But, when they become your close friends you can know about their problems which are not one or two. They have problems in their life,indeed,they just have decided not to make others sad or feel sorry about them, when there is nothing they can do. They can become great and loyal friends. In my opinion, every body can be like them if they want to.
In reality, we all have some problem more or less. But some people are so skilled to hid their problem under their bright smile :) That's why we can't see their small or big problem and often consider them as the people having no problem.
But still, we all meet at least one person like @Emily said in the mirror :)
I don't think that there are anyone doesn't have any proplem !
it won't be a real life if it doesn't include problems !
