Welcome to the forum Deke.
Your length of service was very similar to mine.
Personally speaking, I felt guilt and shame about leaving initially, then sorrow because I was leaving my family and the only friends that I ever knew.
Then anger set in, thinking about my wasted life. I am in my late 50's with no qualifications and crap job and no pension. I would have loved to have had the opportunity to go to university and who knows what kind of job I would have now.
I am now at a stage of acceptance of my situation and a great sense of liberation (especially on a Saturday morning ....no more field ministry and on Sunday, which used to be totally taken up with meeting in morning, lunch at the hall then ministry in the afterrnoon. I have got my weekends back. YAY!! The novelty never wears off ha ha )
Despite all of that, I am determined never to be bitter. There were some good times and I had some very close friends who I loved dearly.
I hope that you enjoy your freedom.
