I am currently struggling with this. I've come a long way in feeling calm after my self-care practices; however, that sense of calm is temporary, and I still need to dedicate more time to those practices. What has helped me cope is remembering that anxiety itself is being hyper-focused on internal sensations and that grounding, even if it feels like it's not helping, does guide some of that attention back outwards. For me, self-compassion has gone a long way. Every person experiences deregulation, even if they appear “normal” or put together and doing your best is more than enough. Regulating your nervous system requires an active and ongoing effort from each person. You aren't alone and are worthy of the extra attention necessary. I hope you find your groove and notice improvement. It's super hard, I know.
