Chastity and orgasm denial discussion

i spent eight days locked in for a scheduled period. it could have been the longest one yet. but on thursday, after six and a half days, i got unexpectedly unlocked. i was put back into chastity on friday. something odd occurred on wednesday. i visited mistress to complete an assignment at her house. i wasn’t anticipating being freed, and we didn’t talk about it. after finishing my job, i lingered for tea and conversation. all seemed well when we said goodbye and returned home. but once there, sitting down made me reflect on the fact that i was still locked up. sadness crept in, bringing a genuine sense of depression. i can’t quite put my finger on it because i had felt okay earlier. does anyone else go through this?
