How can I become a more organized and less destructive person?

This is advice because I really need it.

I hate it. Everything I touch breaks, fueling my anxiety. My sandals, all destroyed from walking too much. Toys? All gone. My phone? Display broke for the 7th time now I think. Anxiety problems? I feel like I annoy my girlfriend. Clothes? Not a single bit organized.

I am wanting to die at this point. Nothing works. Christianity doesn't feel like it helps, nobody feels like it helps. My mom just abandoned me to a point, saying "I did all I could for you OP, you are now on your own."

I am fresh out of high school.
