if a time machine does exist.

if a time machine does exist,
and time travel wouldn't change or cause any effect of the future,
i would come visiting myself in the past, the teenage me in secondary school and high school.

i would just tell them that they're doing great, even the best they could. that they didn't deserve any bad treatments they're facing. that it's not their fault, and they'd done more than enough that they built the future them better. they might still be getting hurt in the future by many things but trust me it wouldn't last long. i hope they could try to never keep any of those anger and hatred in their heart because those are what make it difficult for them to have a peaceful life. i just want them to know things did get better, perhaps not for their relationship with other people but at least it did with everything they've achieved. i am beyond proud of them for staying this far. so let's stay for another and more years ahead.
