If it's in good condition, maybe you could consider donating it to make a wig for cancer patients? Might take away some of the sting if you know it's going to a great cause. I cut my hair from almost to my bum to chin length when I was around 13. I was sick of every hairdresser I went to refusing to cut it and saying it was beautiful long. It was a huge relief and felt so good! No regrets at all, and it does grow back. Now I've gone from long to short and back again plenty of times.
