This isn't a spell, it's a technique I guess you could say. Simply put, because magic operates from our subconscious and since it sounds like you have bad luck that doesn't leave, the problem is actually in Ur subconscious beliefs. In an ancient text (don't remember the name) a person came to ask for a blessing but the teacher simply said "see it and believe in Ur desire". He did what was instructed and came back victorious.
I think this is more important than any spell u might find because spells operate on our vibration not our words we say. Find what is really bothering you, confront it and confront it. Finally feel what you want as it is happening, and if what you want is happening you're not worrying if its going to happen because it is happening. When your fear leaves, your vibration rises and makes your life more fulfilling.
Because that's what magic is not a quick solution to our problems. Hope it helped and Blessed be!
