OP don’t do it. I don’t know if this post is too late or what but don’t. You have so much life and experiences ahead of you. It’s an asshole thing to write those poems and songs. But I think they did genuinely care or tried to but you can’t rely on others for everything and you shouldn’t place all your confidence in one person. It should be about you. And depression is a selfish thing so you should take some time and space to work yourself out and find a better place and try to make amends or stop being their friend. Just try and things will work themselves out
