My Mother and I Constantly Fight.?

She is always constantly nagging at me. I love her, but there are times when I just want to slap her and tell her to shut up. I know this sounds like being a regular teenager, but I'm afraid things tend to get more serious. She's constantly condescending, not only to me, but to everyone else in the family, and there are times when I dream about doing a murder/suicide. I'm not going to ask if this is normal, but some resolutions WITHOUT counseling would be lovely.
