I’m sorry your struggling so much
If you have hypothyroidism that can be a huge factor in moods and difficulty losing weight... that’s just medical fact.
Do you have a eating disorder? Yes no maybe so. Your thyroid Med could easily need an adjustment, some people need tweaks monthly. It’s not uncommon for people across the bored to just keep eating, my husband is a stress eater.
I doubt that you will find anyone that hasn’t dealt with feeling depressed ( truly a diagnosed illness) or just feeling depressed due to situational things and it not be a chemical imbalance
You didn’t say with auto immune disease and that fine you don’t have too, I have Psoriatic arthritis and psoriasis which are autoimmune also and they can cause more troubles with finding stability mood wise.
If you have had a full physical work up and you are being actively treated and blood work confirms it then you need to have a full psych exam and start sorting out your symptoms. There is a Med now for “binge eating” but most Doctors feel CBT therapy as first line treatment , after all you have to find out “ what “ is driving it.
What was your Vitamin D level, that certain can cause depression.
But yes .. you owe it to yourself to get in with a Pdoc and start treating the symptoms. Some people get a BP diagnosis in a few weeks some in months and I’ve known some its taken a year , Many Pdocs like to observe over time. It won’t effect treatment , you will get tossed onto the Med Merry Go Round so be prepaired
You will also need a Therapist. CBT really can help you sort of feelings, and learn coping skills which everyone needs.
I’m glad your here posting about how your feeling and struggles you face.
Keep posting
