Yeah, it becomes an addiction, the body goes into withdrawals. It is especially true for sugary foods.
I think as the body starts to crave the feelings, people can't even imagine themselves to be without them - it becomes part of their identity.
I'm not taking into consideration medical conditions because those operate in their own realms under their particular rules.
Yes, this is a different thing.
In my experience, going down into depression feels a lot like drowning -thing I also have experience with. But trying to get to feel often doesn't work. It's like that numbness of the the body when air is almost gone.
I drowned and was resuscitated on my 8th birthday. After the initial panic, I accepted my fate and I don't think I have ever felt that kind of serenity since.
I have had 2 experiences with that. During the first one, I wasn't feeling anything actually. Everything was calm. I remember watching stuff going on from the bottom of the pool. Until someone dived in and took me out. It feels weird. I mean yes it is a serene thing. The second time, I was nearly drowned by my brother and cousin at the beach. We were playing with a ball and someone threw it past me. They pushed me into the water and they were pinning me down. At first, I thought they had realized I was there, but then I started to get desperate and struggle to get out. It was just moments before I ran out of air that I somehow managed to pull myself out and hit both of them in the face with my elbows.
