My mood has been flatter since about month four and I genuinely cannot work out whether that is the drug, the deficit, or the fact that I no longer have my main coping mechanism.

The bit I cannot resolve on my own is how people separated a drug effect from the ordinary consequences of a large deficit and disrupted sleep, because I cannot.

Not looking for reassurance. Looking for the part I have got wrong.

I'd say therapy should be AVAILABLE to all GLP-1 patients, but requiring it as a precondition for treatment would create an access barrier.

Not everyone can afford therapy. Not everyone needs it. Some people do just fine with medication + lifestyle changes. But for those with emotional eating, body image issues, or disordered eating history, therapy is extremely valuable.

My recommendation: make mental health screening part of the initial assessment, offer therapy as a recommended adjunct, but don't gatekeep medication access behind it.

Anxiety increase on mental health: counterintuitive, but losing weight rapidly triggered anxiety for me. Change — even positive change — is stressful. I was anxious about loose skin.

This is more common than people admit. A therapist who specializes in weight management has been invaluable. Don't neglect the mental health side of this journey.

This matches mine closely enough to be worth saying so out loud. Nothing to add that would improve it.

Adding the clinical framing, because it changes how the question reads.

Mood changes on mental health: I want to be transparent — I went through a rough patch emotionally around month 2. Not depression exactly, but a weird flatness. Food was my main coping mechanism and without that, I had to develop new ones.

Therapy has been essential. I'd strongly recommend anyone starting GLP-1 therapy also invest in mental health support. The physical transformation is only half the journey.
