I am so sorry to hear about
your father and to have to deal with the ID being so rude and heartless is beyond comprehension. You need to move forward with all the resources you have and find the right LLMD to help you.
My first visit to my PCP's ID Dr referral was horrible and I was told yes I did have lyme [+IgM on WB] but I am now better - I had 21 days of Doxy @ 100mg 2X a day, he would have only given me 10 days. I should be feeling better in two or three months when my immune system has a chance to shake itself out !!!
Second ID [same pratice, different Dr - they scheduled me twice and then the receptionist was rude and told me to either keep the 2nd appt or cancel - so I went again] - I was checked for co-infections [negative] and told the same few months I should be back to normal but if things got worse she would be ok with 10 days of Doxy if it seemed merited.
So please get started on the LLMD asap, I have found a long waiting list and a lot of summer vacations standing in the way of my appointment with an LLMD. I wish you the best.
Take a few extra minutes and know that we are thinking of you and it will get better, slowly...don't let the nightmare today discourage you, keep fighting and check in here for support whenever you need it
