Trauma can be lifelong if it isn’t worked through, but some trauma can be worked through (and hallucinogens are showing promise of working through trauma quicker than medication&talk therapy alone). I think the actual emotional trauma response however is individually maybe 10-15 mins long at maximum, but feeling the emotion often causes you to think other triggering thoughts or behave in a manner exacerbating the trigger, thus making an individual 10-15 minute thing take hours to sort itself out.
