Hi missbethy,
It sounds like there's a possibility that you have Generalized Anxiety Disorder (GAD). What you describe is not an uncommon symptom of GAD. You should make an appointment to see a mental health specialist about it. Usually meds, therapy, or a combination of both can help you get a handle on it.
Welcome to the forums! I hope you find all the help and support that you're looking for. I look forward to getting to know you better!
Good luck,
Greg
