Get your hands on and read Denise Linn's Sacred Space book (she has another called Feng Shui for the Soul but i think Sacred Space is the one you need) OR Karen Kingston's Creating Sacred Space with Feng Shui. Both books will instruct you on aspects of house clearing and more importantly charging with positive intent, along with feng shui things like object placement etc. Hard to make suggestions without seeing your place, but some typical things include hanging pictures that show images of you all looking happy, or images that suggest abundance and ease. Keeping a healthy happy plant inside your entrance or in your main living area could help. Also, think about the flow of energy through your house from the front door...is anything blocking it? Or is your front door in a direct line with your back door (if it is, you need to hang some chimes in between the two to stop the energy rushing straight out the back). Reading the books is helpful because it gives you a chance to think about what you want to create in positive terms, rather than focussing on the run of bad luck you have...sometimes that shift from negative to looking forward to the good that's coming your way can help in itself, kwim?

and I hope this is the beginning of a run of good luck, created by your conscious intent .
