Feeling of negativity, fear of mind.

Dear sir, at first I had GERD problem so I took endoscopy to confirm result came has GERD. Then later I feeling like swelling in posterior part of neck. So I took ultrasound result came has small cervical lymph node less than 1cm. After that I got fear so took MRI neck because of little pain. Result came has lymph node enlarge of 1.3cm. doctor said no need of fnac. But for past 5 to 6 months I'm feeling like I have cancer, lymphoma, because of swelling. I used to touch and feel like that. I can't able to concentrate on anything always fearing of future like what will happen if I have cancer. I'm getting fear to visit doctor. What he will say to do like biopsy. I'm thinking like I will die soon. my life has gone. Right now I don't know whom should I see. I'm crying literally. I also attach my report. Thanks
