Around two months ago, I (16M) had a vivid dream that I was diagnosed with "blood cancer". When I woke up that morning, I discovered that a lymph node in my neck was swollen. I didn’t feel sick, everything was fine except for that node. It didn’t hurt or anything either. 

I brushed it off the best I could thinking that I was just going to get sick. But after two weeks went by and another lymph node swelled up beside it, I went to my family doctor who said it’s probably nothing but ordered some blood tests to check for any infection just in case. 

I tested negative for Mono and Lyme disease, my thyroid is fine, and there’s nothing that points towards any infection. My doctor has no idea why my lymph nodes are swollen now 

It’s been two months since it started. I have 3 swollen nodes in my neck now and an appointment for an ultrasound on September 20th. During those two months, I’ve been obsessively researching what swollen lymph nodes mean, and Lymphoma cancer is always there. I’m worried that they will find something on the ultrasound and I’ll have to have a biopsy. Im really dreading the ultrasound and I’m completely convinced that I have it. 

I cant stop thinking about it, this is really scary. I’m scared about my health a lot but this is the first time I’ve been completely convinced somethings wrong
