Why would you need assistance with that?
Will you actually let your feelings and flaws be stronger than you, are you that weak?
First of all forget spells. Look into yourself and fix yourself, don't seek an answer outside because what you erase will eventually come back to you anyway. What's inherent to you, or to the human being, can never be erased, only disguised.
Be alone for a while. Say no to every possible relationship. Meditate on yourself and your feelings, and when you're healed, start thinking on saying "yes" to a new person
