Hello :)
I completely understand your situation. My best friend is a licensed social worker and specializes in CBT therapy. She also cannot speak with me like she would with one of her clients so what she does to help me, is to offer advice of what I should start looking into to manage the anxiety itself. She HIGHLY encourages seeing a therapist that specializes in CBT as CBT is proven to work for anxiety disorders. I started to see a therapist last year, but she left, saw someone new and he was a total quack. So I ended up giving up, but I am trying someone new next week.
I have also tried guided meditation while going to bed. That seemed to help ALOT. I also tend to do something active while having an attack such as clean, organize something, play with my cats, cook, and also those adult coloring books are AMAZING at keeping your mind and hands occupied.
Is your hubby on any kind of medication? I am getting ready to start a low dose of Lexapro and work my way up to the 10 mg. My doctor started me at 5mg but it was too much. She told me that people with anxiety WILL feel the side effects more than a person with just depression. Maybe he should try some medications.
He definately needs to seek some kind of outlet for his anxiety. I am doing my best and keep track on this website and trying new things daily. I recently discovered the yoga breathing techniques which really really does help. Breathe in for 4 seconds through the nose, hold it for 7 seconds, and release through mouth for 8 seconds. I also do EFT tapping therapy at home. Try looking up Brad Yates tapping on you tube.
Good luck to you and your husband. I know how hard this is. I have been suffering from panic since childhood. Feel free to msg me or ask any questions as we go through this!
