I would yell at my younger me, kick him, and beat him until the younger me would show his parents his middle finger, tell them they should have adopted an engineer instead of having me I would make sure he would pack his things, leave the house and carve out his own path.

After all, studying, working and eventually falling out of a job I loathed (in more than one way) always turns out to be the basis of my mental issues so given the opportunity, I would have done anything to save myself. Even a good beating probably would have been less traumatizing than growning up in the knowledge I should have been somebody else.
