What to do next....

Salut tout le monde....i just graduated (ba in finance) now im doing my masters and im very uninterested and unhappy since 2/5 (portfolio management and financial engineering)of my subjects i don’t get a word of what my dr is saying i just sit there completely clueless and believe me every class mate says the same and we can’t do anything abt it....i feel like im wasting my time and i dont have any work experience ( just one intern) and to be honest ever aince i graduated i feel less and less interested in this field (so not just because of my dr) and thinking maybe i should do my masters in management but still hesitant. What do you think i should do? Whats the advantage of finance/management mix or does it even have an advantage...? Give me an advice what should i do next cause i feel very lost and uninterested and not gonna lie i always feel afraid or anxious about everything and im finding hard time enjoying where i am right now.

Merci d’avance
