We do park those emotions. I had to go through an awful workplace bullying claim a few years back. Actually writing about the experience and subsequent interviews plunged me into such despair I considered suicide was a better option than returning. I didn't realise until that moment how much the stress had impacted on me. But it was also enlightening. It gave me the strength to say no more...and regardless of whether my claim was accepted or not (it was) I quickly found a new job.
All was roses until 5 months later and found the darn lump.
But...recently I walked past the volunteer ladies making pink flowers at the local shopping centre...all in prep for pink October. I actually had a full on anxiety moment and reduced to tears. I fully recalled going in with my bald head buying my flowers and T shirt and having to sit every 50 m due to exhaustion whilst there. I think we all have a little PTSD as memories are stored with the emotion. Digging up the memories releases it. Perhaps it's good to let it out every now and then and then box it back up for another day.
