Joy is not very Permanent thing as is not happiness either. Actually closest thing to a permanent it’s when we accept our fate and learn to be happy with it.
From my past Suffering I’ve learned not to escape the present suffering. Often I still do wrong decisions that actually cause more suffering. Best response towards the present suffering is to accept it and learn to love the fate. Amor fati.
So with this in mind, if I do not feel joy it’s sign for me to still work on myself. Solution is not to seek joy from other people, or substances. What I’ve found is that mostly takes some rest, quiet meditation and clarification of priorities.
Nature of suffering arises something that we did or didn’t do and then we start to feel helpless. However, once we regain the sense of control and are able to do something the joy starts to come back.
Start from the inner joy. Drink only to celebration so to speak. Strengthen that which is right with the world focus less on everything else.
