My first person perspective of where "I" am has physically changed!
.. Could I have induced brain damage?
... On top of that, it feels like the person looking through my eyes is not "me". !!
.. Also killing me, is the blank mind. No daydreaming, ability to imagine and visualize has gone. No internal chatter. I used to have a million thoughts per second in that bubble where "I" was located. That's the configuration that Quaker32 identifies with. Hence why this feels foreign and I HAVE NO IDEA WHO I AM (I know my name, factual details etc).
.. I had a moment of psychosis last week where I thought I was Jesus. That hasn't returned, luckily.
Your ability to precisely describe your symptoms in exactly the same way Buddhist onepointedness and/or insight meditation would leads to at particular points, makes me seriously doubt any brain damage. But rather a spiritual crisis, because of not being prepared at all for such things to happen.
Buddhist meditation usually as one of its first steps tries to silence the chattering mind. Once silenced - for which many practitioners need decades of dedicated practice - there are 2 benefits here and now:
First a pleasant abiding - since the self-limiting chatter has ceased and our ability to feel extended consciousness and bliss becomes unlimited (due to your Christian socialization hence feeling like an all-loving Jesus).
But secondly, and more the ultimate purpose of such meditation, the ability to directly experience reality as it arises and passes from moment to moment (without interference of our believe-systems through ceaseless internal chatter). In all it's experience-able aspects of body and mind: bodily sensations, feelings, thoughts, emotional fabrications and consciousnesses associated with each.
Out of this experience arises the knowledge how everything thus experienced arises and passes due to causes and effects in co-dependent manners. In it's dependence on 'out-side' factors and fickleness its utterly impermanent (anicca), therefore never able to give lasting satisfaction - but only stress in the end (dukkha), and ultimately not what could be identified with as a self, I am, or what belongs to me (anatta).
Which should bring about the kind of detachment and equanimity of the saints described in Buddhism, which there is considered the highest happiness possible for sentient beings.
.
Sadly, you don't have the conceptual framework to enjoy with detachment, but instead think to have to dumb it down with medications.
All I could advise in this quagmire is to direct your attention to experience the impermanence in everything. Though you won't get your old 'configuration quaker32' back - since it all was artificially made-up to begin with - but the pain, confusion, trauma, suffering will be seen for what they are: fluctuating phenomena arising and passing due to co-dependency in an ever changing world without lasting happiness. And so much, much less overwhelming.
