life is full of ups and downs so sometimes you have a long down period, other times it's a long up. last year was the worst i've had in a long time, i wasn't cursed, just life. and sometimes you will stagnate and the universe/gods will try and force you to move on. so perhaps if you sit down and look at the big picture of your life you might have an 'aha' moment and find an opportunity.
even if you weren't cursed it's a good idea to cleanse and protect yourself and your home on a regular basis to make sure no negative energy builds up [also, when you move into a new place it's a good idea to clean away any energy left behind from the old owners] there's many ways to cleanse and protect so try looking up a few methods and do what works best for you. a simple one is tu burn sage and waft the smoke throughout your house to cleanse away negative energy. [sprinkling sea salt water works too] just be sure to feel the positive energy and focus on your desired intent of cleaning away negative energy [or curse in this case] for yourself you can soak in a sea salt bath and let the water wash away any negative energy [i use a sea salt scrub and charge it with energy so it cleanses as well as exfoliates] it takes practice to start feeling energy, but you should feel lighter, or at least calmer after cleansing.
for a protection spell, again, there's several things you can do so research and find the best one for you. a simple one is to hang a protection symbol over the doors, or say a chant. same with yourself, you could wear a protection symbol, or say a protection chant. you can also ground negative energy, charge positive energy, and shield yourself daily to help keep negative energy away.
after you've done the cleansing and protection, just go about your life confident it worked and it's a new day. dwelling on every little bump will bring negative energy and you could unknowingly curse yourself. over time negative energy does build up so i suggest getting into a cleansing habit. personally i cleanse/protect my home once [sometimes twice] a year and cleanse/protect myself at least once a month [especially after stressful days it's a good idea to cleanse away any energy] good luck to you.
