I'm so sorry, Bryguy. Relationships are hard enough, but toss in Lyme disease and they can be extremely hard! I'm married and had those issues.
Honestly, it sounds like your GF needs to understand a bit more about
these infections and how they affect us - we can't always be as responsive as others would like us to be. Anger, anxiety, depression, depersonalization, and derealization can all make it very hard on relationships.
If you have any anxiety or depression issues, I would encourage you to get medications or supplements/herbs to help you deal with those. If you are dealing with the depersonalization or the derealization (sounds like you might be?), then that just takes time and healing and she will have to be understanding of that part. But you can kind of meet in the middle on many things.
Hopefully, these links will provide you with at least some ideas - maybe you can get her to sit down and read these links and then watch the movie too?

I think couple's therapy is good, but you should be seeing a Lyme literate therapist so that they truly understand your issues. A therapist can't understand how much these infections can interfere with our thinking or our ability to communicate, much less how we suffer with depersonalization and other things unless they have had this training. Depending on where you are located, I may even have a listing of a Lyme literate therapist. You can send me an email if you would like to find out.
