I don’t know who is right. I do know that what you are describing is what I hear from many teens. It’s part of adolescence to be worried about your looks, to have unstable emotions and to be anxious about many things. It’s a stage of life where self-esteem is shaky. You are involved in figuring out life and your place in it — not an easy task.
If you continue to be concerned about your mental health, the first stop is with your doctor. Sometimes extreme emotions are a result of hormone imbalances. Sometimes a person like yourself is over-worried because you have no way to know that what you are feeling is within the range of normal. Your doctor does know and can treat you if necessary or reassure you if things are fine.
I doubt very much that you have 5 serious conditions. The Sanity Score is not a diagnosis. It is intended to help people narrow down their concerns so they can do further research. In your case, your doctor is your best resource.
I wish you well.
