I suspect you would find more info in the Lyme disease forum as the members there are a wealth of knowledge about this disease.

Living with a chronic illness ( and you appear to have more than one disorder) puts you at risk for developing anxiety and depression.
Sometimes, it can be difficult to know whether you are feeling down because of your physical health, or if you do actually have symptoms of depression or anxiety. Sometimes it can be both. If you're unsure if what you're feeling is a normal reaction to what is happening in your life, talk to your doctor, another health professional or a member of your health care team. With open discussion, they can help you to work out what's going on and whether you could benefit from additional advice or treatment.
I have a serious medical disease and I understand what it feels like to have your feelings bouncing all over the place.
I hope the articles will be helpful for you.
Big breath and know you are stronger than you think.
