Yes we all do, but we must overcome them, even when they seem like it will never end. We can look at it like a challenge in our life, and we can and will make it better. There is nobody without problems, there is always something. Some people are just better at not "showing" their problems to others. Even those that are very content have something that troubles them...what ever it may be. My advise to you is focus on the solution, not on the problem.
