RE: It Is All Gonna Be Fine At The End, If Its Not Fine Then It Is Not The End!!
The Buddha said that "existence is suffering" and "its cause is desire".
The desire for things to be different than they are moves us away from the nature of life as it is revealed to us in this very moment.
It would be wise to temper our desires, learn to accept and as you say have patience when we find we are struggling against life as though it were something that is happening to us rather than with us.
