I would like to answer with a question:
Have you ever had the experience of feeling fully content? Like staying in a situation and wishing for nothing more and nothing less?

I had this experience, but only on very very rare occasions. As I perceive a great suffering in the world, I would say that one fizzling out pain is replaced by another one setting in and being painless (either mentally or physically) is a state of being rare to find. That may sound pessimistic, I prefer to call it realistic :)

Addiction can either be pointless or a strategy to cope with pain. ... Actually, .... I would say every addiction points to something deeper. It is not the cause of pain in the first place, only a symptom to express and deal with it.

Does your mother still live?

You too, take care.
