Quirks,
Similar feelings here. This summer I will have been out for 12 years and it still pisses me off.
I have an insatiably curious mind and one of the things that makes the angriest is that I denied myself an education. While I was in, every time I brought up the subject of going to college, my ex-wife and her parents would give me a ration of shit about it...it is dangerous for your spirituality, you don't need higher education to serve Jehovah, blah, blah, blah....you know the BORG reasoning. There were multiple reasons that I bailed on the BORG, but that was one of the biggies.
When I bailed on the BORG, in 1997, I was 41 and I almost immediately went back to school. It has been a long but incomparably satisfying haul. I got a geolgoy B.S. in 2004, a geology M.S last December, and am finishing the last assignment for a J.D. which I expect to receive in May. While I am extremely happy to where I am now, I am bitter because I have done all this by the time I was 30 instead and a much longer period of my life would have ended up being richly enhanced.
So, no matter how long you're out, once you've been run over by the bus there are lasting impacts that never go away. Everyone has suffered different specific injuries but it still leaves all of us scarred.
Hang in there man.
