I had an experience along these lines when I was 22 and meditating daily, which ended up turning into anxiety and somewhat frequent panic attacks. I ended up giving up my daily practice for about 10 years because of it. My frame of reference was the very common Theravada practices you encounter in the west, but my experiences didn't make sense to me until I began reading Mahayana teachings and found my way to Vajrayana practice.
So I'd say the framework is important, but to be flexible with it as you encounter things that aren't maybe a part of the core teaching. In my case it was the teachings on emptiness that opened things, which is something the Theravada doesn't emphasize (although it's there).
I think what I wanted to emphasise is having nothing at all can leave you in a bad position. Hitting these dreary spiritual states without any philosophic or religious framework that can provide perspective is like being lost out in the sea without even a life preserver, much less a boat.

I'd like to give a heads up that this can and may come crashing down[1]. The 'Dark Night of the Soul' is a very real phenomena, and it can happen out of nowhere -- just a normal meditation session.
I'd suggest giving a search to 'mindfulness' and 'mental distress' or some such, if you continue on with this. It is really helpful to find a framework -- like Buddhism or Raja Yoga (https://en.wikipedia.org/wiki/R%C4%81ja_yoga#Comparison_with...) -- before diving too deep, to give you something to fall back on when it happens, otherwise it can result in quite unpleasant, hard to overcome and understand situations. Edit to add: The specific framework doesn't matter as much as having one at all (Christianity/Islam/Buddhism/Yoga/etc.).
