Hyper vigilant

I noticed when my caseworker came to see me today that every time her phone vibrated, I jumped. I genuinely think I have ptsd from my childhood. I can’t have any notifications. Phone calls are hard for me. I’m always on alert wherever I go and everyone just constantly makes me jump. I hate it. It’s exhausting. She finally said “don’t worry. It’s just my phone.” And I laid back in the car seat and sighed. Because I’m genuinely so tired of it.
