Lately I've been noticing something strange.

I'm just living my normal life but I start noticing I've withdrawn socially but but like completely and my mood is suddenly way worse than normally, anhedonia and lack of motivation get way worse... Few days later, i notice my social anxiety got worse as well and I'm no longer leaving my apartment, not even going out to buy food cuz I'm scared of people. It just keeps getting worse for 3 weeks i guess, it's crazy because I completely isolate myself and I'm more terrified of my neighbors and sounds and I'm really scared I'll get raid by police or smth... Ik it's irrational but I can't help it , the fear and that expectation is overwhelming and gnawing on me all the time. Also I'm unable to organize anything, plan things etc., I can't enjoy anything at all everything irritates me and just overall i can feel something's very wrong.

And that's when it hits... This fucking episode or what... After 3 weeks of this, there comes a day when I get so dumb... I literally can't think, use my brain, I can't understand anything and I can't really even speak and stuff because it's... That's not me idk but it's disorganized and this all happened today since the morning it was getting real bad. My movements become very robotic, it feels so bad to move because it's as if i can't control my body well, it's just so robotic and shaky... My whole body trembles a little. My pupils are dilated and it's a little difficult to articulate. I also started tasting the water differently, it tastes so disgusting but I can't stop drinking it by tiny sips, i noticed I've been avoiding water today completely before it began tasting like this. In fact, everything tastes completely differently. My eyes are wide open and I'm not doing it on purpose. Paranoia skyrocketing. I'm so so so scared and fearful of everything... It's very hard to function, to do the most basic tasks and even my salive tastes horrible.

And the best part? This happened to me a few times already over the course of idk... 3 months maybe?

What the hell is going on, what are these episodes?
