“It’s your anxiety”

I have a good idea I’m suffering from Lyme disease. And my doctor takes me as a joke. It started as chest pain then i noticed a swollen gland under my jaw 7 months ago. I thought nothing of it. I then suffered from irregular periods, painful ones at that. It as caused me to have bowel issues. I ran a low grade fever after ovulation sometimes it would spike up to 100. I casually felt my neck while scratching it and felt a palpable node. Then one near my collarbone. I went to my doctor 2 weeks ago and he felt the reactive lymph nodes were swollen. I was put on Keflex for 10 days and still suffered from the same pains. It caused more lymph nodes to swell in my neck. I asked if I could get blood-work done to find the underlying problem and he just put me on Bactrim for 10 days. I have ringing in my ears, most of the pain is on my left side. In my joints and even in my bones and muscles. I notice it more when I’m sitting down. I need blood drawn ASAP and my doctor takes me as a fucking joke and hypochondriac.
