Generally, retainers in Texas are refundable, minus the attorney's work and expenses. You have a couple of options: you can tell your attorney you're dissatisfied and hope she changes; you can send her a letter stating that you want to cancel her representation and asking for a refund of her retainer; or you can try to retain another lawyer who will ask for her retainer back so they can get paid as well.
You can certainly change your mind. You should have a contract you signed when you hired the attorney, and you should check that contract to see what the terms are that govern termination of the representation and return of funds.
