Many teens are dealing with depression, its not normal but is treatable and addressable through therapy. Dont know that SB is the trigger or if other things happening in your teen life triggered it.
Ask yourself this - why do you think you suffer with depression and low self esteem? Is there any reasons that might've triggered it or caused it?
