I can't believe I'm even here right now. I feel terrible posting because I'm not sure if I have lymphoma but I've had chronic health anxiety for 1 year now. 

I need some help or advice. I'm only 18 yrs old btw (turned 18 in dec) The reason why I think I've got lymphoma is because one night I woke up with my armpits hurting, which prompted me to have a feel and I discovered a lump which was initially an estimated 1.5cm large. This has now grown to around 2cm or more. I have a low grade fever which is at 37.3°c but this sometimes decreases or increases depending if I'm panicking or not. I am known to get panic attacks if my anxiety peaks. 

I also have a small cyst (reduced in size) which is on the side of my neck it is defo soft. I also have a smaller lump at the top of my neck to the right of my neck which seems harder.

I've also lost weight (I'm a skinny person anyway but this has made me feel worse) my parents say it's down to my anxiety and they get v annoyed at me when I keep worrying. I've got 3 symptoms of lymphoma. I do not have an itch, my stomach doesn't get particularly upset unless it's my anxiety. It can get bloated however. I haven't got nightsweats yet but I am hot all the time now. I did get a really bad flare up of a rash (all over back and front) when I had a big panic attack yesterday but it went away as I calmed down. 

All in all I can't keep my mind at rest and I'm starting to belive the worst (lump under armpit is hard and movable). Any help is appreciated  :)

p.s I do feel fatigued and can't tell if it's because of my relentless anxiety or something more sinsiter. I forgot to mention I have the shakes too when I'm hotter/anxious and my extremities are much colder than the rest of my body.
