Hi Shawna, I wish I had read your post much earlier! I hate vacations too, but I think our problem isn't "vacations", exactly. I think it's the way we feel about our family(in this case, your mom I suppose). It makes us miss that comfort zone you mentioned.
My family stopped going on vacations a long time ago precisely because we don't get along well together and various other issues, but if I had to go again I wouldn't have the slightest desire. Although I like traveling and seeing new places, I prefer to do it alone rather than in their company. Am I ungrateful? Who cares!
I also have anxiety problems, above all when I find myself in new places or situations, in the end I always manage to gather courage but it is difficult to manage everything myself.
The vacations imposed by others are a cage for me and nothing more, but when I have the chance I will do many of them alone or with some friends, if they want!
There's nothing wrong with wanting to go home when you don't feel comfortable in a certain place, who wouldn't want that? Maybe one day you too will be able to find a way to really enjoy your vacations, but if you really discover that you don't like traveling very much, well it simply means that you still have a thousand unexplored places to discover in your imagination!
Each of us is unique in our own way and there is no right way to live our life, there is only what makes us feel good
