Op. Can you identify what causes your negative or stressed feelings. Firstly Other than your weight. Is there something in your life making you unhappy? A relationship, job, finances, family, friendships, kids?
the weight also is potentially making uou unhappy and possibly uncomfortable or unwell. Sore joints, skin sores, mobility issues, breathing issues, blood pressure, sleep apnea etc, dealing with this all day every day will have a very negative effect mentally and leave you struggling to deal with any further stress.
could the aggressive bingeing be a reaction to not wanting or being able to deal with it? To a feeling of helplessness?
when did the bingeing start? Can you pinpoint that? Where in the world are you? I note you say you can’t afford a diagnosis. Is this due to medical insurance or job impacts?
I think it’s worth starting your journey by speaking to a doctor. Every journey starts with a first step, and you deserve to be happy and healthy. So taking that first step on your own journey is really important.
