Hi CR and welcome! I am sorry to hear that you are experiencing such worry right now. It is both a wonderful and awful thing that we have so much information at our fingertips through the WWW!
Many of us here who suffer with health anxiety need to steer clear of symptom searching on the computer. It will almost always lead you to believe the absolute worst-case senario of anything that you are feeling!
I am sure that your stiff neck and swollen gland are the result of a passing virus that is nothing to worry about. Stiffness and glands aroung the armpits, neck and jaw area are pretty common with colds and flus.
That is not to say that you shouldn't see your dr., however. Especially if you run a temperature, or if you start to feel worse. Explain to your parents that if they don't want to see the dr. themselves that is fine, but you are your own person and want to go! They have a responsibility as your parents to take care of you and that includes regular health care.
If you can't get them to help you, I suggest asking another trusted adult in your family to get involved, or maybe try showing them your post and responses. Your health is important, and you have the right to see a dr. regularly, regardless of their personal feelings/phobias.
You have found a great place for support, sharing and information. I am glad that you have found us, we understand how you feel and what it is like to worry about these things. Rest assured though, that you are going to be fine. Keep posting with us, but try to stay away from the symptom searching okay?
Post again soon and let us know how you are feeling,
"Courage is not the abscence of fear, it is feeling afraid and doing it anyway!"
"It is when we are most lost that we sometimes find our truest friends"
