Advice

Hi everyone 

Im currently seeing my gp (although I think they're not very concerned) because I am very worried about some symptoms. I have been suffering from extreme fatigue, weight loss, bruising, sweating, strange unexplained rashes and now a swollen lymph node which is immobile and painless, although I think it has gone down a lot now. They've done a blood test, but I'm convinced it's going to come back normal. If it does, am I right to still be worried? I can't help but feel like it's unlikely that it's not cancer, and I'm particularly worried that my symptoms seem to match with Hodgkin's lymphoma. I have a strong family history of either cancer or a supressed immune system. I have an appointment later today. 
thanks
