Hypochondriac here 
Just over a month ago I was bitten by a couple ticks (not on the same day), one was removed by my gp and I was given antibiotics, people told me my gp was being silly and the chances of the tic carrying lymes is very slim so I decided not to take the antibiotics. Tic bite looked fine, no ring, no rash etc..
Fast forward a few weeks and I come down with what appears to be a bad cold/flu, not like me at all to be I’ll let alone during the summer. I’m on day 8 of said cold/flu and I just feel like sleeping all day, I go out for a couple hours and then I need to sleep, I’m struggling with my part time job (sleep before I go, sleep when I get home) and I wake up tired in the mornings. A few people have suggested I get tested for lymes but I don’t have all the symptoms, I have had cold symptoms (cough, runny nose) which are not linked to lymes but I have also had a achy neck (before I started feeling unwell) and a racing heart which I put down to stress.
Is it worth asking my gp for a blood test? I feel silly asking as I will have to tell him that I did not take the antibiotics he gave me and because he will probably think I’m being a hypochondriac.
