The world is not child sized. I believe you when you say being tall suck. I am 1,5m, something like 4"11. So, the size of a child. I fit in cars, but I need a cushion. Lot of counters are so high that only my head sticks out. Finding clothes sucks too. My feet often don't touch the ground when I'm seating on an adult chair. I have to climb so much things. I can't reach all my shelves, even with a stool. Sometimes, sinks are a little too high.
I'm absolutely ok with my size, and I really think being small is easier than being really tall, but the world is not made for people my size. Really not.
