I had my first dtr.(40 yrs old)at 18. Honeymoon baby!
I have to disagree with you on your saying that since your mom was 17 when she gave birth to you "might be a lot of your problem."
When my dtr. tried to pull every trick in the book when she was a teenager, it just didn't work(most of the time)because I was young enough to remember all the stuff I pulled, and got away with it. That's another story!
Her younger sister learned that she wouldn't get away with anything by watching what went on between myself and her big sister.
I'm a very lucky mother that has two beautiful dtrs. who turned out to be pretty darn good girls.
Of course, they both have their problems. What kids don't.
BUT...one of these days, you mother will get to a time in her life where she will want you to be with her, either to be just to talk to, or to help take care of her, and I hope you will be able to be there for her.
It's so sad that you can't have a good relationship with your mom, but you can go on to be a great person on your own.
Good luck to you Stacy!
