I'm sorry to hear about your anxiety. The good news is that there are a lot of things you can do to make it more manageable.

As others have mentioned, it is important to find a therapist who specializes in anxiety disorders and is trained in Cognitive Behavioral Therapy (CBT). Sometimes this is combined with Exposure and Response Prevention (ERP); usually ERP is used for phobias and OCD, but it might be useful for other types of anxiety as well. Stay far, far away from therapists practicing Freudian psychoanalysis; that will probably make things worse. Your therapist must be a specialist in anxiety disorders and he or she must be trained in CBT.

Doing relaxation exercises and/or meditating can be part of your toolkit as well, though I personally have not found meditation or relaxation to be cure-alls. They help, but by themselves they do not take me very far unless I'm also using other tools to manage my anxiety.

Some people find some relief through medications. I take Klonopin (Clonazepam) regularly and it has worked wonders for me.

Another important part of your toolkit is educating yourself about anxiety. If you are able to read without too many problems from your injury, you might check out the book Dancing with Fear, by Paul Foxman. I found this book very useful when I was first educating myself about anxiety. You can also check out online resources such as the NIMH:

In sum, I think the best approach involves a combination of (a) CBT, (b) meditation and/or relaxation, (c) educating yourself about anxiety disorders, and possibly (d) medication.

Good luck.
