It sounds like something negative has latched itself onto you. Do a cleansing of your body and soul, and perhaps your home. I'd suggest doing this as soonly as possible.
Visualize or imagine in your mind your heart rooting through your body, through your feet into the nature and world around you. In your heart, a light forms and grows, pushing outwards, it pushes away the negativity, it burns it. It becomes a bubble around you. Imagine your energy forming a bubble the same way around your daughter and those you care for. Protecting them, Cleansing them.
Burn sage in a small nonflamable bowl to ward away any negative consciousness. Then if you'd like, burn a black candle for protection (Keep it somewhere it won't cause a fire) and put bay leaves in the corners of the main living area of your home. Carry bay leaves with you (Putting them in a small tea bowl on a chain can help).
I hope this helps, if you need more, or need me to help cast a protection for you, please mail me. I won't ask for a penny, I will however help you however I can.
