Most people, Bipolar or not would take a trip to just get away from there troubles or lousy job or any number of s hitty things. The fact someone would "assume" you will need a hospital stay is ridiculous ! so what if you do? or dont?
You had a great time and shoving BP out of your mind for a while it good great perfect thing.
Sometimes you just have to turn a deaf ear to the people in your life that haven't a damn clue about BP. I have one person in my life that just has to ask me crap like " hows your bipolar? are you taking your meds ?do you feel okay? are you manic? depressed? " My reply is " Hows the weather?" ... that's all, I refuse to discuss it.
I'm glad you had a fun trip with loads of memories and great times.
Hang in there
