I agree with SorryShaped, have something you can control.

I actually (unintentionally) went to one of my most triggering places I could go to today in a fit of rage. While I was there, I did nothing but shout and talk angrily at the air. I left when voices in my head began to panic (meaning I was sure to follow suit). I might've been there for a grand total of four minutes but I managed three minutes and fifty-five seconds more than I ever have before. Afterwards I stared at the new water cooler for a while and made myself think about the story behind it and how it got there, more specifically when it got there. When is key because it was there way after everything that happened and that fact kept me grounded.

Honestly, I'm still feeling anxious over it and I feel as though I've been awake for a whole week doing hard labor. It's exhausting to say the least and it's definitely hard (understatement of the year), but it is possible. I hope it helps. And, hey, even if you're only there for a minute, that's better than zero.
