Will it get better?

My story began in 2022 after consuming a marijuana cookie. It was my first and only experience with drugs. I had a bad trip and wanted to “escape” that moment as quickly as possible. I woke up with severe derealization. During the first few weeks, I would wake up with a racing heart. Somehow, after about a year, it started to calm down, and I was able to function normally.

Since the beginning of this year, I feel like everything has returned, even in a worse form. I can’t sleep, and when I do, my dreams are very strange. I experience panic attacks so intense that I have to walk around, and I can’t calm down. My skin constantly burns. I cry all the time. I feel nauseous and can’t eat. I spend whole days just lying down, and at most, I might go out for a single walk. I have strong derealization and depersonalization, and I also experience visual snow; the world feels artificial, and people seem unnatural. Time feels very slow.

The doctor treating my HPPD prescribed pregabalin and citalopram, which I’ve been taking since Wednesday. Will they help? I feel an awful emptiness in my head, and my thoughts are entirely consumed by what is happening to me. Is there any way I can help myself? Has anyone experienced something similar and recovered? Could TMS (Transcranial Magnetic Stimulation) help in my situation? Every day feels like a horror.
