I Am Mad, Sad, Disappointed

I was supposed to go to Disney World with my friend and her sister who is special needs. I wasted so much money on the trip. I spent about $320 on the ticket and the hotel. Then I spent even more on the bad park food that was overpriced for its quality. But what I'm disappointed in the most was that I had a bad time at Epcot because I felt it was really boring so I pined all of my hopes on Magic Kingdom. We barely got to do any rides at Magic Kingdom because when we got there, my friend's sister's medicine was left at home by mistake so she kept perseverating about wanting to go back to the hotel. That it was too hot and too many people and didn't want to go on any rides. She kept trying to escape and say that she wanted to leave. We tried ignoring her but she wouldn't stop. Then her parents ordered us to go back to the hotel so that she can sleep for an hour and hopefully change her mind after. Since we couldn't leave her at the hotel by herself, we all had to leave. We didn't return at the park because she woke up at 8:45. She still didn't want to go to the park. We would have to get dinner, wait for the bus to bring us to Magic Kingdom, probably only giving us an hour. We didn't want to feel rushed so we never went back. Our passes expired on that day so that would be the only chance we had of going. I get that my friend's sister can't help being who she is but it wasn't fair to me that I couldn't have a stress free vacation. Disney World is not across the street from me. It's a four hour drive there. I had the worst time during the trip. My friend felt guilty for what happened but she kept speaking for me saying we had a great time despite everything. Speak for yourself! I'm probably never going to get the chance to go back to Disney anytime soon all because my friend's sister ruined everything. I'm so mad at both of them. I looked forward to this trip for months and in the end, I had the worst time. Normal people go on vacation and have the time of their lives. It's just too much to ask for happiness on my end.
