Within my 25+ years in the wellness industry I have seen hundreds of people change their relationship with themself through the power of somatics (aka - body based healing).
Like you, I struggled with high-functioning anxiety for many years. On the outside everything appeared "good.' I had my own business, 2 great kids, a husband. But inside it felt like at any moment everything was going to come crashing down. I was a tight ball of anxiety. Overthinking, overanalyzing everything. Struggling to get a good night sleep, feeling completely exhausted and burnt out. Thinking that if I could just escape for a short amount of time everything would be ok. But even after a vacation, the feeling didn't go away.
It wasn't until I learned how to tune into my body using somatic practices that I was able to change the relationship I had with myself and anxiety. Instead of trying to make the anxiety go away, I learned how to UnShame it and use its energy to enhance my life.
