Google it. I did and there is a ton of stuff on there about breaking a curse or hex. Do some research. I think with as much time as you are spending asking for help you may find a way to do it yourself. If you do and have questions along the way then we are here.
1. Your family's "abilities", and your own dreams, just point to a practitioner background.
2. Believing that you have back luck in money matters /etc, creates this bad luck.
Positive thinking goes a long way.
3. Don't place so much stock, in what "others" say. POS practitioners are only there to tell you, what you want to hear, and gain a paycheck.
4. Magik is personal, and you just can't dive in. Even if you did some research online, you will still have to practice the ritual -- and use all your willpower towards your desired outcome.
Try to cleanse and protect yourself and your family. that should help out. you can try the blessing technique of the elements, or any spells/rituals. And yea,rituals do help for protection. Hope this helps!---Rinx
Maybe someone in your lineage cast a luck spell that essentialy borrowed luck from future generations. Hope thats not taking advantage raven. Its just what i saw.
Dowse yourself in consecrated water in the night outside. Enter a trance and visualize the curse manifesting as a being. Then talk to it and ask it to leave and stay gone, if your religious you should pray to your god to make it do as its told. Then, if it refuses to leave use a banishing spell or think joyful loving and good thoughts. imagine those thoughts becoming pure energy, make a grabing gesture over your heart and push the energy at it. You might just corrupt it's curse with a blessing, thus undoing it.
Maybe you could ask tarot or playing cards what to do. There are many sources of information about the meaning of cards. Or you could try this:

I don't know if that works, I just found it on the internet.
