I started university recently and it's been quite stressful. I must take existentialism as an elective and it is truly driving me mad. As someone who has suffered with SEVERE depersonalization/derealization in the past, studying existentialism is very difficult. My struggle with dp/dr was truly the worst thing I have ever gone through and it traumatized/scarred me big time. Since starting this class, all the worries about "what is real", "am i dreaming?", "how do we know what is true and what is not", and all the what ifs are flooding back. I just worked myself up to a panic attack thinking about all this and I feel like my head is spinning and my brain feels "tight." I feel like I'm losing my mind, which is my worst fear. The last time I struggled with depersonalization/derealization, I became housebound for months and could barely eat/sleep. I can't even stomach the thought of re-living that experience. How can I continue taking this course without internalizing everything, overthinking everything, and driving myself mad???
