I think we all have at least some of those types of memories... I know I do as I had an abusive spouse who moved me 28 times in 26 years---whenever I began to make friends and establish myself.... I had to learn to look back at all those "goodbyes" as leaving that segment of life and moving on to the next.... not abandonment. It's a mindset, again... and one that is fraught with negative intrusions... but we can overcome the negative and seek only the good...and in most all situations there is a sliver of some good or benefit..even if it was something we learned never to allow again.
