depressed boyfriend... it’s getting worse and i don’t know what to do.

my boyfriend and i have been together for about a year, and he has slowly been opening up to me more and more, revealing that he Actually hates himself a lot. a few nights a week he will go into a depression and won’t listen to anything i say, will only go on about how worthless he feels and how sorry he is. i know getting him professional help is not an option, because of his parents. i don’t know what to do.

i also feel guilty myself for being unable to help him. when i met him i was recovering from a deep depression and a couple suicide attempts, and he makes me happier than i’ve ever been. besides his depressive episodes, our relationship is beyond perfect. we have great communication and chemistry, and we’re best friends.

i really need advice on what to do.
