I'm not saying you are not cursed, but you may not want to just jump to the conclusion of being cursed.
Life has its up and downs. Things tend to get worse before things can get better. That's just life. But what matters is how we react. Our very own thoughts -conscious and subconscious- emotions, etc can cause negative things or positive things to happen.
You may want to determine if it's life or if you are possibly cursed before trying a spell to stop bad things from happening to you.
