Me (24, husband), Wife (22). We know each other since childhood and have been married since last year. 

Since our engagement she developed habits that imo seem to be anxiety traits. 

We are driving around in the car and there is absolutely ZERO reason to be triggered by something but she suddenly gets what she calls “stiff arms and legs” or trouble breathing all the way in and thus having the feeling of not getting enough oxygen and going to die. 

We could go out for dinner and have the best time but eventually the symptoms kick in. 
Her head starts spinning, her arms and legs getting stiff as stone. As soon as she lies flat on the bed she has this feeling of no power and being sucked into the mattress. 

Whenever I try to calm her down she wants to be left alone and I just can’t stand seeing her sitting there suffering and trying to get feeling into her arms by massaging them by herself. 
Worst is that she panics when it happens.  

After the symptoms stop, she can’t stop apologizing telling me that she feels sorry for me that I have to endure all this because of her. 

We are already considering professional help, but is there anything else that could be done beside the actual therapy? 

Any advice is deeply appreciated.
