I'm obsessed with my mom
Are you obsessed with her personality?
No, I'm just obsessed because she's my mom.
It is unnatural and abnormal to have incestuous feelings for your mother. It would be good to find a psychiatrist who you can talk to about your feelings so you can get treatment and change your behavior.
Suck my balls.
Your extreme reaction suggests that you know on some level that being attracted to your mother is not normal. You should talk to a professional to figure out why you are having these feelings.
