I think I might have depression or bipolar or something similar but my family don't believe me.?

well... on the note of anxiety, being bipolar tends to tie along with it... i have both....and all of your mood swings are not only due to your raging teenage hormones but it also is your very obvious bipolar disorder...i do think you also have depression, as well i do...that is the reason for your basic hate for life and non-motivated life style... i also recommend that psychologist, i also have one of those... with all of the problems i seem to have, i know how you feel, i am a teenager to:)
