Welcome Kurteous! Glad you joined and posted. This can be a great place to get support, advice and sometimes feedback we need but don't always want. I hope you have a good relationship with your mom, you said she was df'd but not if you two are close.
You asked for ideas. I say start by sorting out your feelings by reading threads about what is going on in some other's lives which may help give you some perspective and maybe even get a counselor (in the real world) to help with the self destruction you mentioned.
glad you posted and can't wait to hear more about your life and why you left at such a young age. God for you not wasting your entire life in the borg.
