Animals and great pets are wonderful therapy within themselves. I am glad your husband has that avenue. We have a wonderful pointer/lab that is very intelligent, loving, and fun. We've always had great dogs over 34 years of marriage. I even will involve Jesse (our dog) in therapy for certain clients. She is very friendly and for dog lovers, they can find some release. I am disabled a bit, so riding a horse is not an option...however, I do have a nice recumbent stationary bike :).
The only therapist I know in Florida lives in Panama City. He is a PhD and excellent. He does do online counseling via 0366 or phone counseling. I have known him a very long time and would highly recommend him. Not to tell you what to do, but most often it is good for the spouse to receive help as well to learn to live with a person with any form of disability or disorder. When I went through my "season" years ago, I urged my wife to get counseling as well. She found a very good therapist (not a psychiatrist) and it helped her immensely. Often the caretakers have equal if not more issues over time than the one who suffers with the disorder. If you are receiving help, good for you.
PTSD has a plethora of symptoms, expressions, etc. It is a reaction to trauma that is often repeated and each person who deals with this reacts in their way. Anger and anxiety are partners in this crime. They most often go hand in hand. There are many counselors, therapists, online sites and often it takes a few "tries" to find the right fit for you particular situation. The most frustrating item of being a counseling therapist is that it is far from an exact science. Many in my position just use a cookie cutter method and pass out the pills. Most often, that methodology is just a bandaid and not a permanent solution. Also, in many cases, PTSD or any other stress/anxiety disorder, there is no permanent cure but rather utilizing certain tools designed for each individual can give a person a healthy and wonderful life.
My recent bout with a minor relapse was due to an upcoming minor surgery I had yesterday. I had an excessive amount of anticipatory anxiety, but I did put all the tools that work for me in place and was fine before the procedure yesterday. All to say, no one is exempt and this caught me off guard. So, I'm human and I embrace that and what a difference it makes to accept one's self and not make the mistake of living up to unrealistic or someone's expectations. It is amazing to me the amount of pressure our culture, family, friends, and worst of all our own beings put on ourselves to be perfect and live a performance based lifestyle. That mentality only increases the tendency toward PTSD, anxiety, stress, etc.
Well, I wish you and your husband well. And time to get to work. I hope some of this helps.
