I have a friend that has had PTSD for 10ish years. There was an event many, many years earlier that she hadn't really thought about... but then her hair started to fall out, and she'd suddenly experience these flushes of absolute terror. It was hardcore. She was exhausted all the time, and the meds she was on made her put on a ton of weight, despite being super fit anyway. It was brutal, and we spoke about it all at length. She had a science background and started a whole psychology degree because she had learnt so much and had such a strong interest... she manages it pretty well now... but I think it still pops up every now and then when she doesn't keep on top of things.
