Absolutely.
To prevent myself from doing something impulsive in those moments, I self-harm, consume some "herbally enhanced" edibles and induce couchlock until I fall asleep, fall down internet rabbit holes for hours, or do something mindless and crafty.
I won't keep items in my house that could be used for an impulsive suicide. When I rented a tank of pure helium for a work-related function, I wouldn't allow myself to bring the thing home until it was completely empty. I don't own any belts or firearms, and avoid purchasing rope that might be suitable for bus-catching. That isn't how I want to go. I do have a method on hand, but it wouldn't be suitable for an impulsive act (if not planned appropriately, someone might find me while I'm still viable... I'm not taking that chance).
I'm sorry you're having a hard day. ❤
