Small hands

by Helpmepls

I am 150 cm tall and my hands are max 16 cm. I have a classic guitar and I am a beginner. I've been struggling to get my hands to make some chords right, while there are chords that I totally can't play without forcing my hand until it hurts.. Each time I try to "practice" it (thinking maybe I'll be able to make it right finally), my hand hurts. I wanted to ask if I should consider buying a new guitar that is 3/4 and acoustic? (I realized only a few days ago that the classic has thicker neck). Or should I keep practicing and my hand will get used to that.?
