Broken Inside and Out

Ive been depressed for a long time. First it was small, but every little thing kept adding to my pain, and its like a mountain of sadness now. Recently, I thought I got over the worst bits, and I became a listener. It went really well at first... but then, on my third chat, I met a suicidal person. They shared their story, saying that they wanted to die because they couldnt find love. I happen to be aromantic and asexual, so I had no way to help. But they refused to go to anyone else after me, and said I was going to be the last person they would try. So I spent hours pleading with them, using every tactic I could think of, but in the end, I failed. In the process, I revealed all of my deepest thoughts and emotions, and they basically destroyed my self esteem, ruined my temporary happiness, and added yet another boulder to my mountain of sadness. They criticized everything I did, used my words against me, and said, You wont care if I live or die. But I do. I care for plants above people, and people above myself. In my mind, everything is more important than me, and I am stuck between fearing death and fearing life. I cant do anything, and Im too afraid to ask anyone for help, too nervous to tell anyone what Im going through. Now, Im responsible for a death. And if the person Im talking about somehow reads this, I just want to say: leave me alone. Youve already broken me enough; theres no need to break me further. Dont die. Live so that you can help someone. And live as far away from me as you can go. Please... can anyone make me happy again?
