My Girlfriend broke up with me. I’m going to kill myself

I can’t do this anymore. I can’t go on living. I loved her and she was my everything. She left me because of all the everyday stress, and she tried to help me but I just kept falling back to darkness and she’s tired of it. Our relationship was nearing a year, as we were together for 9 months and I blew it all to sky hell. That’s it, it’s over for me. I’ll never be the same so what’s the point in living anymore?
