Do you have a counselor/therapist to talk to? Have you always worried a lot or this a new thing? I ask because I started worrying incesantly in November of last year. Once I started talking about a certain problem that I stuck in denial, I went back to my normal level of worry as described above. You might also consider talking to your doctor.
My T mentioned a book on anxiety. But it concerned itself more with social anxiety. If you worry about everything, it might be more like Generalized Anxiety Disorder (everythings got a name-ugg). I am not making a diagnoses of course. So don't take it as one. I'd suggest trying a counselor and having the counselor guide you on some self-help measures. I found some books at the library by looking up social anxiety. But, I'd try a counselor because your's sounds very annoying.
I wish you luck. By the way, one of the books claims that anxiety is highly treatable. I liked that. I hope the book is right on that.
