Depression help

I need some advice . I do not like to talk about how I feel but I am starting to think I have depression . In high school I was involved in self harm for about 3 years and never really reaolved it was just told to stop or this and that will happen . I still have tendency’s to want to do it. I can sleep for 8-10 hours at a time and wake up to take a 2-3 hour nap . I am not happy with my life even tho there are things I should be happy about . I just have no real emotions with things or people .. my boyfriend refers to me as heartless. Cold and just an asshole. Any suggestions or advice on what to do with my life 😕
