Suicidal when quitting caffeine?

I have a lot going on right now so there are variables but I've never felt so unable to cope with life. I quit in early January and have extreme insomnia, suicidal ideation (badly) and pain sensitivity and my immune system is screwed. Anybody else get suicidal after quitting? This is all so hard. I can't drink it again because it hurts my teeth.

Edit: there was a post 3 years ago in this group by a guy with similar experience and many people responded saying they had similar experience so I know I'm not alone in this. My neurotransmitters must be off. I also had a few DM me saying they had some similar stuff after I posted this so please don't be rude. I deleted the rude comment.
