1. Yes, it is possible for Lyme related anxiety to start within 2 months of a tick bite.
2. I don't know. There is evidence that urine from an infected person or animal can transmit the bacteria to an uninfected person (if I remember right, someone in the Under Our Skin movie got Lyme this way...), but little is known about
this (how it happens, whether it requires more than just skin contact - ie, a wound, rubbing one's eye, etc. may be necessary for transmission to occur, etc.). I do know that deer are not where ticks get infected from - rats are the primary source that the ticks get the Lyme bacteria from, and then the ticks pass the Lyme along when they bite people, deer and other animals.
3. The best way to answer your question is to recommend that you see "Under Our Skin" - this documentary explains the political and financial reasons for the ignorance amongst most all doctors that leads to lack of proper diagnosis and care of those with Lyme Disease.
I've read that a mix of Eucalyptus Oil and Rosemary Oil (ratio of 1:1) will repell ticks, but I haven't tried this myself.
