Hardships are not a sign of being cursed. They're a sign that you're alive in a fallen, sinful world. Life is tough. Stop comparing your life to other peoples' lives. God has given each of us a path to walk that is for us and nobody else. If you have a grievance over something in your life, you need to bring it before the Lord and surrender it, not wander into outlandish voodoo-type thinking of being cursed. Jesus was materially poor during His ministry years, He was persecuted, He was lied about, He was made fun of, He was betrayed, and ultimately was killed. Was He cursed? The apostles were beaten, jailed, driven from place to place by persecution, and many were murdered. Were they cursed? There are children starving to death and dying of curable diseases right now all over the world. Did someone put a curse on them?
Come on, dude. Get your head back into right thinking. Not only are you NOT cursed, but if you have your health, a roof over your head, and clothes on your back, no matter how impoverished you might feel, you're already ten steps ahead of a LOT of other people who would gladly trade places with you.
