Hello mossmothh and a warm welcome to Cancer Chat, 

It's normal to be anxious and as you have a long history with anxiety the discovery of this lump on the left side of your neck is bound to have exacerbated your anxiety. You've done the right thing though in getting an appointment to have it looked at and while you are waiting to be seen it is normal for your anxiety to feel worse due to all this uncertainty. Do talk to your GP about these anxiety attacks you have had when you see them on Tuesday if you feel it is hard to keep them under control. 

I know it is really hard but try not to worry too much or anticipate what it might be as there are so many things it is likely to be other than lymphoma. The best thing to do to avoid thinking too much about this is to keep busy and distracted if you can and avoid looking things up online. I can imagine it is hard for you to do this at the moment but it will help you feel a little less anxious. There are helpful tips on this page to help you cope while waiting for important news. 

I hope you will also hear from others here who have been through all this before and that they will be along soon to share their story with you. 

Keeping everything crossed for you that everything turns out fine. 

Best wishes, 

Lucie, Cancer Chat Moderator
