Even if you live in the most rural of communities, you should be able to find someone, whether it be a social worker specializing in therapy, or an actual psychologist, well versed in CBT, which stands for Cognitive Behavioral Therapy. Neuropsychs are admittedly much harder to find, and they are usually on a shorter term basis, (as in interpreting a Neuropsych Assessment and then offering treatment recommendations).

I have to admit that I really do not feel like the person I was before my accident. I am better. I meditate, I am more relaxed, and I take things day by day. I admittedly still have some issues from my (what turned out to be) severe concussion, but with CBT and an SNRI called Effexor, I was able to get my life back. It really sounds like you are suffering from major depression.

There is a great book that may help you: "Full Catastrophe Living" by John Cabot Zinn. Most libraries have it--if not it can be ordered on Amazon.com.
