Answer
The Bhagavad Gita clearly explains who is responsible for the difficult circumstances of a human being.
Some circumstances arise from destiny, and that destiny is formed by our own karmas from past lives. Therefore, we should accept that destiny with dignity and without becoming distressed. To remain sorrowful again and again is not appropriate.
At the same time, we must also be mindful that we do not worsen our future destiny by our own hands. For this, one should refrain from bad deeds, from tormenting and causing sorrow to others, and should perform meritorious actions to the extent possible.
However, the question is: how does one deal with present difficulties? One must find solutions. Merely enduring is not enough; it is necessary to find a way out wisely.
Let this be clearly understood: any deity can render assistance in one or two particular situations, but they cannot alter the larger picture of your entire life. The power to change that picture lies only within you — in your thoughts, your contemplation, and your sustained efforts.
Recall that verse of the Bhagavad Gita that I have quoted many times: 'Neither does the Lord create anyone's actions, nor the fruits of their actions; all these arise from a person's own nature.'
Therefore, by all means go to Bhagavati Durga. She is immensely powerful. But the primary role will always belong to your own actions and your own thinking.
Therefore, apply the intelligence of problem-solving.
Read the Gita every day — do not merely recite it. Read it, understand it, and put it into practice in your life. You will find complete guidance for the cessation of suffering right there.
Towards the end of the Bhagavata Purana, Sri Krishna makes a harsh but truthful statement: if a human being were to invest even half the time and attention in their own efforts that they spend going to deities for the fulfilment of desires, they could accomplish their tasks on their own. You know how, and on what basis, He put a stop to the worship of Indra.
If merely calling upon God and performing rituals could transform life and remove poverty, then the Muslims, who pray regularly five times a day for a total of roughly one and a half hours daily (supplicating to God in namaz), would not generally be among the poorest. Even five percent of Hindus today do not engage in such prolonged regular worship.
Therefore, worship God without selfish desires (nishkama upasana). Love Him.
But for the accomplishment of worldly tasks and the removal of poverty, your own planning, hard work, and industriousness will prove far more effective.
