AloneinOh,
You are not alone. I could have written that myself a couple of years ago. You describe exactly what I went through, and it is not over for me yet.
Please. Do not make the mistake that I did and confront your parents with it.
You need to wait a couple of years or more to settle down and regain your composure first.
You are a very lucky fellow. My wife signed up and her and my kids are in it too. Its not pretty.
Settle down. Sit down and have a smoke (singular) and a beer (singular) if you feel it is getting to you. Consider it medicinal.
Now that you have realised what had been done to you, life will get better. Much better. Much MUCH better.
Stick around and keep in touch. There are some wonderful people here who can, and do, help us through this difficult period.
Regards
Chris
