Ds17 who has autism, is currently away in Belgium with my sister, there’s only 4 years between them and they generally get on very well. It’s the first time he’s left the country without DP or myself. They booked it back in August and were intending to go to the Pixar experience, but neither of them did thier homework and it finished shorty after booking. DS was umming and aahhing about going but then ultimately decided he wanted to still go, (We would pay her what she paid so she didn’t lose out in money) we double checked if he still wanted to go on Sunday and he seemed genuinely excited. The were in London for the day on Sunday and arrived in Belgium this morning. Thier train was delayed just out side of Brussels for 1hr so DS was already overwhelmed, sensory overload. I am already a hot mess and my sister now keeps messaging me telling me that DS is asking why they booked for so long, that he doesn’t want to do anything, he’s been on his phone etc, now before she booked it I warned her this could happen, she was like yeah it’s fine and so far all she’s done is text me complaining, how she’s not spending her holiday sitting in a hotel room etc, now I understand that but she knew this could happen if something goes wrong and he gets over stimulated. I’m pissed off she keeps messaging me, when there’s absolutely nothing I can do. I’m already pissed off because when she booked the train back she told me originally she was booking the morning, but she actually booked late afternoon which means they will be wandering Brussels for 4 hours after leaving the hotel. I’ve just gotta hope and pray he’s okay, he suffers with anxiety. I can’t just tell him to come home because he won’t travel home by himself and I don’t think he’s allowed, and honestly I don’t want him to in case something goes wrong. I did tell my sister to use this as a lesson to not book anything past an overnight with him. I obviously don’t want him to ruin her holiday. I don’t want to keep messaging him just in case it makes him worse. Obviously I know my case is slightly complex, but how does everyone else deal with thier teens being out of the country without them. I, trying to keep busy but it’s easier said than done, with most other things I can but this is my autistic first born son and he’s not entirely like other kids. I’m proud of him for trying because honestly there was a period I thought he was going to refuse to go.
