With you consciously working to find the best in yourself, I believe your husband should be celebrating your efforts as opposed to dismissing them as a waste of time. Not everyone accepts the challenge of understanding themself better and finding the best in themself. In my opinion, you're thoroughly inspiring.
With your husband suggesting you 'learn to live with it' and that's it, he may as well be saying 'You need to learn to live with not understanding yourself better'. For me, coming to understand myself better can feel like a full time job. One of the many benefits of being so dedicated to this process involves all those 'Aha!' moments. I love those moments. I'm a 50yo gal and am still regularly having those liberating moments, gradually solving the puzzle known as 'me'.
I can't help but wonder whether you're a highly sensitive person. While being a HSP can feel like a curse at times, it actually comes with many benefits. Being sensitive to any shifts of activity in our body can give us certain advantages. Example: I can always tell when I'm becoming slightly dehydrated. Sounds weird but I'll start to feel a slight change of pressure in my head, coupled with what feels like slightly dry skin on my face. When I feel these things, I'll start drinking more water. I never used to be this sensitive and would always end up with a headache, wondering what was causing it. It's rare I'll get headaches now because I can feel them coming.
Someone once said to me 'Be conscious of your body language, what your body's trying to tell you'. This is a body language of a different kind. Learning to interpret what our body's saying is skillful. Our body 'speaks' for a reason. Personally, I don't want to dull down my sensitivity because it serves me well. My goal is to better understand what I'm feeling or sensing. Can you sense when mental tension/stress has become so great that it takes physical form, in your muscles? Can you sense when mental and physical activity within you is completely relaxed? What about when mental activity is so great that it manifests as physical hyper activity? Has your psychologist given you some breathing techniques in order to help you vent that level of activity in your mind and body, in helping to manage anxiety?
If you have an incredible natural ability to sense subtle changes in your body, you could consider your husband doesn't have this same ability, therefor he can't relate to the need to 'learn the language'.
