As Krizalid said, it is always important to take care of your mental health. Asking for professional help can improve the way you deal with emotions and thoughts.
That being said, I suggest taking the best of that situation (the "feeling" of being able to watch the emotions and mindstates impersonally, and the knowledge of the possibility of finding progressive peace and tranquility through mental training, like the one offered by the Buddha through the Noble Eightfold Path), but keeping in mind that such experiences are conditioned and impermanent. Try to not get attached to it, don't become obsessed with trying to feel it again, and pay attention to not use this as a way to increase (maybe unconsciously) your "ego" or ideas born from conceit, about an "I" which is "more spiritual" and superior than everyone else.
I'm not saying that what you felt was false nor a delusion. I'm just suggesting to keep your feet on the ground, and to maybe use this as a motivation for getting in touch with the mind and its processes. Buddhism offers a lot of tools, knowledge and strategies for knowing the mind better, for understading the motivations behind our deeds, and for learning how to deal with such underlying processes.
I wish you the best, and feel free to ask here whatever you may need to be answered (related to Buddhism, of course).
Have a wonderful day!
