The thoughts just hit me out of nowhere, and it's like I actually experiencing falling down the stairs. I feel a jolt of adrenaline and my body tenses up. It's like it really happens and I can see it and everything. So then I'm like, going down the stairs all tense and slow trying to prevent what feels like is inevitable, even though I know it's not. I already work myself through it in the sense that I do still make it down the stairs, but it happens so fast that I feel like I need to figure out how to prevent it in the first place. I also feel like working on the stairs issue is pointless, because I know my mind will quickly replace it. It's always something. Like tensing up and hesitating crossing the street because I get a sudden, intrusive thought that the cars are going to hit me, or having to avoid the walnut tree because a walnut is going to fall and crack me in the head. Just endless, dumb thoughts, but my body reacts to all of them.
