New to lyme- LLMD and advice?

Hello everyone,
My name is Carly and I am a 20 year old female in Pottstown, PA. I have a pretty long story for my age, but I will try to quickly summarize. I have been feeling like crap for years, but it has recently gotten much worse. my main issue has been fatigue. Also have had muscle aches, daily headaches, stomach issues, anxiety.
about a week ago I began having muscle aches that were unlike any that I had been having. The pain was excruciating in my legs, so I couldn't sit still. On day 2 of that I realized I had a fever so figured I was just sick. I work in a daycare in the infant room during the summer, and I go to college for occupational therapy. The next day I started having watery diarrhea which lasted about 2-3 days. Then I started to feel a little better. So I went to work this past Friday and felt the worst I had felt all week. It hurt so bad just to pick up the babies. That night I started running a fever again. The fevers were all low grade, about 100.5. I slept about 20 minutes that night because the muscle aches, mostly leg, came back and I sat on my bed rocking back and forth the entire night. In the morning I convinced my mom I needed to go to the ER. My temp was 101.8 when we got there and my heart was racing the entire time. They found low potassium and treated that and gave 2 bags of fluids. The Dr then said that my Lyme test was unequivocal, neither positive or negative, so he gave me 21 days of doxycycline and told me to follow up with my Dr. He also said he thinks I have the coxsackie virus, as I have large ulcers in my throat.
So that was 2 days ago, my fever went back to being low but I don't think it has really broken at all since. And my throat is killing me, mainly due to one large ulcer I can see, and terrible headaches. My mom is supposed to make an appointment with my GP to get the results of the western blot test, but I am not fond of my doctor at all and I've heard these tests can be tricky.
So now I am trying to find a good doctor to go to, not too far because my mom hates travelling and was hoping for some help. I have a list of 4 doctors so far, but I'm worried none will accept our insurance. So if anyone could help me find a doctor near Pottstown, PA, we could probably travel about an hour. Also, since I am new to this I would love some advice on anything I should know, especially about getting accurate tests and diagnosis.
Thanks to anyone who read all of this and for help in advance!!!

Welcome to the forum Carly! I'm sorry you've had so much pain and discomfort to deal with. Hopefully you can get in to see the doctor Beth mentioned. Keep us posted on how you're doing. There are a lot of knowledgeable people on here and you will get support while you go through treatments too, so stick around. I wish you the best!

Thank you all for your responses. Beth, I will shoot you an e-mail about the doctor. I have a lot of questions circling in my head as I continue to do research. My main concern is my mom's lack of concern. She is not interested in working on this at all and keeps acting like I am not sick. So I am planning to call the list of doctors tomorrow and maybe go to my grandmom, but if the western blot comes back negative my mom will have no interest in pursuing it further.
So some questions I've been wondering about:
If none of these doctors take insurance, how do people pay for it? I read something about trying to get reimbursed yourself from the insurance company. Any other suggestions about this?
With the tests, can doctors tell how long I have had the infection?
And lastly, does anyone know of any good resources I could use to inform family and friends about lyme disease? Also maybe a good one for my mom to read to help her understand.
Thanks!!
