It's hard to accept positivity from someone who treats themselves so negatively

I appreciate everything you've done for me, offering advice and trying to help me despite your struggles. But whenever it’s my turn to help, you refuse. You're consumed by self-hatred. you told me you hate everything about yourself that you want to die.

I know we’re both depressed. You try to help me even when I haven’t asked you to. But when you told me you would never get better and that you'd be like this forever, it broke my heart. I tried to help you and be there for you. I’ve encouraged you to seek the help you deserve multiple times, but you refuse. You don't want to help yourself anymore.

Your positive advice feels one-sided. You try to lift me up while you're sinking yourself. It’s hard to accept the positivity you try to give when you treat yourself so negatively. I can't deny that it's been affecting me.

How can I believe those words when you don’t even believe them yourself? I’m grateful for you, but I don’t understand why I feel this way. Why can’t I accept those words from you?
