welcome back! i wondered where you'd gone off to! so
that's where.
i'm so sorry you went through this.

if i recall correctly you did not have a pdoc but your regular GP was scripting your meds, is that right? i wonder if you had a pdoc if the hx would have been "necessary."
from the different stories i've heard, the care in hospitals varies a whole lot, from pretty decent to really bad. i suspect however that going inpatient is almost always traumatic/stressful to a degree. at times, it still may be better to go in than not. and that partly depends on the quality of care.
i went inpatient, once, voluntarily once. it was ok, but i got less than i had expected. i had been in stop-the-world-i-want-to-get off state, non-stop and for too long, and it allowed me to do that. they did sort out my meds. but when i got out i too fell apart totally at first: instant overwhelm and anxiety.
i felt better relatively quickly, however. i hope you do too.
i am glad your mom is there for you. i hope today is a good day, for you, to start with.

p.s. once you settle down, if in fact your GP is scripting your meds, i would seriously consider pdoc-shopping.
