It sounds to me as just you should try to find ways of ridding negativity here are some ways to help that have worked for me:
Take abath with sea salt and light some candles that are lavender scented.As you cleanse yourself visualize the negativity being removed from your soul. When you let the water out just look at the water as carrying off the negativity that the sea salt absorbed. Make sure that you extinguish the candles after usage.
Another thing to do is burn sage toserve as a ward to get rid of negativity also.
If it is a hex or a curse(I'm sorry if they are the same thing and I used a double negative) I suggest that you wear an amulet or some protection charm to shield you from harm.
Also another thing to look at is that it is just part of life. We all have our ups and downs and sooner or later things return to better. There is a saying I have found true: "Things get worse before they get better." Another saying for the optimistic approach, "Even when the clouds block out the sun and everything is dreary the sun still shines behind the dark grey clouds"
Things will get better. Keep your head up high!
