I hate last minute changes in plans

I am having serious issues regulating my emotions and reactions when plans change unexpectedly. Like sometimes its not a big deal, and Im still finding myself seriously spiraling.

This week, my husband and I had plans to go camping with his family this weekend. We are going to stay in this nice area near his grandmother’s grave (I promise its cool and not creepy lol) and camp and spend some time cleaning up the grave and taking a moment to remember his grandma.

We were originally going to do this in the summer but plans were not well thought out and his folks had to cancel. This October weekend was chosen by his sister as it worked with his niece’s time out of school. At the time we reschedule I voiced that October was late in the season, so we would have to prepare for some possibly unexpected or cold weather.

Come to Thursday late night, get a text from his sister that its going to be cold and wet so they don’t want to have to camp. They found a couple Air B&B that can hold all of us for about $300-400 per couple/ group.

I’m so sick of plans getting changed and canceled and I’m so uncomfortable in having to spend hundreds of dollars. Im also sick of other peoples preferences or lack of planning having to change my plans. I really need to find a way to regulate when I get this upset at plans changing, at this point I just want to cancel and not even go and I feel like this will ruin the weekend for me.
