does dr come with existential thoughts? and does junk food and soda make it worse?

to me when I first got dr, everything I thought was normal suddenly wasn’t. everything terrified me and then I started to get existential thoughts. I managed to get over it somehow. 2 years later I got it again. when you first get it, for me It feels like hell. the feeling still lingers for me after the first hit. like, sometimes I’ll be doing something completely forgetting about my dr and then the feeling and thoughts will pop out of nowhere, reminding me of this hell. I also find it that when I drink soda and eat junk food it gets worse... can anyone else relate?
