Well, we cannot make your religion stop considering masturbation a sin. The notion that masturbation is a sin is entirely ridiculous, any which way you look at it, because nobody gets hurt. But your religion states what it states, and we cannot change it. Only you can change the way you treat the tenets of your religion. The most obvious way for you to help yourself is to master what is called critical thinking. I do not see any other options that could be productive for you, but maybe others able of more creative thinking would come help you resolve your issues.
