I've been lucky to have a GP who helped me recognise my addiction to ultra processed food (mostly refined carbs and sugar) as a root cause of my struggles to control my T2. The condition is not formally recognised yet, so no formal support is available, but I have been pointed to some useful resources that apply to dealing with addictions in general. Just being able to attach a label to my struggles has been extremely useful and has given me a useful framework to start dealing with my challenges. I guess it depends on what you are facing and what support is available locally.
