Good Morning. I agree with Confusedli, don't compare yourself to others. There are many levels of Depression and your depression will be unique to you.
I would like to suggest you see your PCP for medical screening to establish your problems do not have a medical cause. From there your physician can help you with getting into therapy.
Your self-esteem can affect how you feel, how you relate to other people, how you deal with challenges and how relaxed and safe you feel in your daily life. Please share all your feelings with your physician as that is the best place to start.
We are here for you so keep posting.
