"Where there is a will, there is a way." You can do anything you set your mind to. That's a fact. You have so much life ahead of you!

Most of your concerns are nothing outside of the norms when it comes to young men your age.

I think it to be rare that family's stay together anymore. So you are definitely understood here. And you are not alone or set apart from most of the rest of the world when it come's to parents being divorced and remarried and even again.

I think that you just need to make some decisions for yourself and follow through with them. Whatever they may be.

I think the real problems might occur if you are so lazy that in 20 years you find yourself writing this same story. I know people that have done this. My best advice to you is.........Don't let it happen to you!
