Hey, Lizzy31! I assume you are worrying about getting old because that will be leading you closer and closer to death?
I think having some concerns about dying is common. Some of us feel more comfortable with dying because of our religious beliefs about an afterlife.
Sweetie, if this fear of aging and death is interfering with your enjoying your life now, then please talk to a counselor about it. Okay?
Me, I try to find something to enjoy every day. I have a lot of chronic health problems, some associated with aging, and I do worry about how much more of a problem they will be as I get older. But I can't control the future.
I hope you can begin to enjoy each day, too, and not worry so much about the future.
