Financial break

Please pray for a financial breakthrough in my life. I am completely stuck as I have to support my family (own children) and my nephews that were orphaned when my brother passed away. I sometimes feel like there is a curse on me as every time I get a bit of money something happens that will require urgent funds. There are times I feel just feel like giving everything because of the struggles seeing no breakthroughs at all. At times I just feel like God has forsaken me, and at the same time I know nothing is impossible with God.
