I feel like you need to burn sage or frankincense and clean out all the clutter and wash the floors. Give everything in your house a good cleaning. As you do that, think of all the negative energy being washed away.
When you shower or bathe, use sea salt and rub it all over yourself. There's also a wonderful bath my friend taught me how to make. Boil fresh basil, parsley, and add a few drops of Florida water (you can buy it online or at a botanica.) Let it cool down. Either put it in your bath for 5 days, or pour some over your head at the end of a shower. It's a negative energy cleanse.
Light a white candle and pray over it
Ask for protection and to cleanse you of any bad luck.
