I Think There's Something Wrong With Me

I really don't know who to talk to about this. I did a search on confession sites and found this one. I read so many of these over the last couple of days I decided to confess here and ask for help.

First of all I'm younger than what I put here but 18 is the youngest. Anyhow I'm a good girl. I get straight As in school. I never get in trouble. I don't do dr*gs or smoke even. I help my mom around the house and sing in the church choir. I have never even kissed a boy or a girl for that matter, yuck! But a few months ago I found the joy of masturbating. At first I just would rub myself through my panties then on to my bare skin. I got to where I would stay up half the night making myself cum. I love it. I can't cum enough. I found that if I ride my bike a certain way I can even cum like that. I love to ride my bike! But I have to be careful when I'm riding with my friends so I don't get caught. A while ago I stumbled across my mom's vibrator when I was putting clothes away in her dresser. I have used it so much since then because it's amazing! I can cum like 10 times in 5 minutes. It's all I think about now. How can I get one of my own. I think my mom suspects something because the batteries keep dying. I'm afraid to put new ones in because if they are dead one day and fresh the next , she'll know! I'm an only child so there is no one else to blame. I'm sure my dad doesn't use it.

Is there something wrong with me? How do I stop thinking about making myself cum all the time? I mean it. It's all I think about every minute of the day.

I dream about when I out of the house on my own and can do it all day long. Do people actually do that? I mean when you have your own apartment and live alone. Do you just stay in bed all day and cum?
I think I would spend all my money on vibrators and spend all my time using them on me.

Should I tell this to a counselor? I think I'd be too embarrassed tbh.
