30 year addiction cold Turkey

So I have been a user for 30+ years, found it at a very young age and it has always been a go to part of my life for dopamine. I am 15 days clean today and just wanted to discuss my symptoms. I am flatlined. Zero motivation, depression, and lethargic aaaf. Like I could just lay in bed and stare at the ceiling. Just posting for maybe some confirmation and support.
