You shared your vulnerable side in this post, this is beautiful to read as often we tend to avoid sadness. Going through little pieces of stuff reminding you of the past is a challenge. You have conquered it. It is ok to cry and feel sad because of your losses. I am sure that your sister is watching you from above and that she is proud of you for making changes.
I also tend to keep things from my past, since early childhood. It is always an emotional rollercoaster to go through those things at an adult age. Thank you for sharing your honest emotional feelings in here!
Hugs and blessings🤗
