I think that I have an anxiety disorder, please help?

Many people are worried about death. You aren't alone. But you have your whole life ahead of you! You should enjoy what you have in life now, and don't hesitate to dream about the future. It also helps if you have a firm belief in life after death, like the eternal life that we were promised by a certain special someone. If you know that you will be safe after you die, you won't have to worry anymore.
