Disordered eating and a difficult relationship with your body can be exhausting to live with. The cycles of restriction, eating, and compensating often carry a lot of shame, and that shame tends to keep things hidden, which makes it harder to get out of the pattern. If you're struggling with this, you're likely dealing with much more than food. It's often tied to how you see yourself, how much control you feel you have, and how you manage distress.
Working with a therapist who understands disordered eating means looking at the emotional patterns underneath the behaviours, not just the behaviours themselves. Therapy can help you examine your relationship with your body, understand what triggers the cycle for you, and build other ways of coping that don't rely on food as a regulator. Change tends to be gradual and non-linear, and good support accounts for that.
