Since you've had a recent blood test, and your results came back fine, thankfully we can rule out blood sugar problems. A blood test however cannot completely rule out Lyme Disease, so this is still a possiblity.
Let me just paste this article below taken from AllExperts. See how many of the symptoms you match and how much you can relate to the description of Lyme Disease.
Disease/Do I have Lymes Disease?
The first thing you need to do is find a Lyme specialist because the tests for Lyme are very unreliable. You can have a flaming case of it and still test negative. Doctors (other than Lyme specialists) are unaware of this fact and/or refuse to believe it. Lyme specialists will treat you regardless of the test results.
There is also the issue of the co-infections that you must be tested for. They share many of Lyme's symtpoms but they don't all respond to the same antibiotics. It takes a Lyme specialist to test for, diagnose and treat these co-infections, some of which are bacterial and some are parasitic.
To find a Lyme specialist, go to LymeNet.org and register. Click on Flash Discussion and then on Seeking A Doctor. Post there with your city and state and someone will email you privately. There is a policy not to post doctors' names on the site due to privacy issues. You will see LLMD a lot on the site and that stands for Lyme-literate MD. They are few and far between so be prepared to travel if you find one. I drive 2 1/2 hours to see my doctor and don’t know where I would be without him. Since you are in NY and there is a lot of Lyme in the New England states, you may find one closer to you.
Good Luck and let me know if you need anyting else.

1. You do not have to recall a bite or have gotten the target rash to have Lyme disease. Less than 50% of people with Lyme do.
2. The tick that carries Lyme is as small as the period at the end of this sentence and their nymphs are nearly microscopic. Ticks are on the move at 35º and above. It’s a year-round problem.
3. You do not have to experience ALL of these symptoms to have Lyme disease. It is also typical for many of these symptoms to come and go or occur once and never occur again.
4. It is possible to have Lyme disease and have a negative test result. After Lyme bacteria enter your system, it tricks your immune system into no longer producing antibodies to fight it, hence, a negative test result. There are also other numerous factors that can affect the results. (Google: Lyme disease negative test results.)
5. Lyme bacteria hide in the spinal fluid, bone, tendons, muscle and nerve fibers and tissues and in many cases are not “floating” around in the bloodstream where they can be picked up on a test. It is a cousin to the syphilis bacteria and very difficult to eradicate.
6. It takes a LYME SPECIALIST to diagnose, test for and treat Lyme disease and any of its associated co-infections. To find one go to LymeNet.org
or ilads.org Lyme specialists do not require a referral.
NOTE: Everyone may have symptoms that appear on this list; however, it does not mean he/she has Lyme disease. If one has numerous symptoms on this list and no other explanation for them, consider Lyme.
