Experiencing trauma-induced disconnection and questioning one's reality?

I can’t tell if this is existential OCD or if something else is going on, but I’ve been having a serious existential crisis-type episode for the past week. Starting with the realization of my own mortality and an impending sense of doom, hopelessness, pointlessness, and despair, which led me down a path of spirituality (mix of Buddhist and Hindu beliefs). That’s in the realm of “normal” for me, and I was feeling amazing afterwards, I felt like everything finally made sense, like I was at peace with the world, nature, and my soul. But then the intrusive thoughts started(about when I realized technically anything is possible in this seemingly endless universe). At first they were about this whole world being fake, that everyone was in on it except for me, that I was being tested to see if I had learned enough/been a good enough person in this life. Soon realized that this wasn’t logical, since I was going off the idea that nothing was real, but if no one was real they wouldn’t be able to lie to me. Then it transitioned into pure solipsism, which terrified me to the very depths of my soul, at which point I felt suicidal (basically “if nothing is real what’s the point?” Kind of thinking) but after a couple of days of ruminating, I realized the flaws in this logic, as well, and was comfortable in the idea that this was false. Which brings me to now. It’s sort of a mixture of the two, I now have an intrusive thought that there’s some force that created this world to test me, but that no one is “real”, that they have the appearance of being conscious like me, but are being controlled by an outside force, that they’re like robots with the appearance of having a soul, but are just programmed to seem that way, that I’ll not be able to see them again when I die and return to the pool of consciousness since they never existed in the first place. I know in my rational mind this isn’t true, but it just keeps pounding in my head that it’s possible, so I can never assume it isn’t the truth, and it’s making me feel so hopeless. What’s the point if everything is a lie? I feel like my world is crumbling beneath my feet, like I’m drowning. The worst part was that I was fine this morning, but was triggered by an existential question I saw posed online, and wound up back here. I’m terrified that I’m going insane.

It’s what if after what if. Existential stuff. What if the way I perceive the world is different from how the rest of the world sees the world. What if my feelings aren’t real? What if everything is an illusion? What if these new thoughts are how things actually are? What is even “right” or “true”…? Why are things the way they are? Why are people the way they are? I didn’t start having thoughts like these until I dated someone who was unlike anyone I’d ever known. He was abusive, manipulative, delusional, overly philosophical and biblical, and didn’t make much sense. The way he viewed the world and people was so off and so wrong and disturbing. He definitely had mental illness and I spent so much time racking my brain trying to understand why he is the way he is that I’ve become obsessed over what is even real and what makes things “ok” or “right”… I know it sounds silly but it is MADDENING and I just want to go back to being happy and blissfully unaware. Life and people and things just seem soooo complicated and scary and NOTHING makes sense. Help. Can anyone relate?

If anyone on this forum is experiencing what I’m experiencing please share your thoughts & experiences with me 🙏. I believe that I have gone insane with the awaful existential thoughts I’m having… I feel like I’m constantly looking for myself , questioning where I am , am I real? Is the world real? Am in a purgatory? What is I’m dead and I don’t know? I’ve become so unsure of myself and of everything around me , I’m constantly doubting reality , I feel so disconnected and feel as though my brain is falling a part and only little parts of it are functioning … I feel trapped inside my own head it’s like own head it’s like I want to escape out my head but I can’t and that triggers severe anxiety. What if I have already hurt someone & I wasn’t aware ?I have forgotten what it’s like to think and live like a normal person ! In fact my brain is now wired to think and live with my awful thoughts 🥲. I can’t cry or react to any happiness or sadness , I often worry that if something happens to someone I love , I won’t be able to show emotion … taking Lexapro but it’s not helping it helps with the depression but not with the intrusive or anxious thoughts. Another reason why I think I’m going mad is for example I’ll be driving on the highway then a truck drives past me, immediately I picture that I had a car accident and I’m not sure if I’m dead or a live because I’m so depersonalised that I don’t know if I’m still here . The hatred at part is trying to explain to a therapist what and how I’m feeling hence I’m reaching out to anyone on this forum who can relate and share their thoughts with me please 🙏
