My OCD / Anxiety / Dissociation / God Knows What has been really bad recently and I've particularly been obsessed with the thoughts of "what if I'm going insane and dont know it" or, "what if the entire basis of my personality is changing and I'm going to become a different person"

I'm scared to do anything right now that isn't just 1) laying in bed being depressed or 2) going to work or 3) watching TV/Movies. I feel like even me being more active online in the last few days is another indicator of my impending insanity. I feel like me potentially drawing online again because I was excited and inspired by the episode is a sign that my personality is shifting and I'm losing touch of who I used to be. I'm forced to over intellectualize every single emotion and thought I experience, and take it as a sign that my identity and reality is crumbling. It's so debilitating. I don't know how I do this everyday and I'm constantly afraid it will just get worse.
