Hey Tai
I started out with shoulder length hair last January (about your length) and I made it to bra strap by December 17!!!!! It can definitely be done.
Now I did a lot to get there, including vitamins and protective styles (not even everyday), but I did it, and so can you.
I've recently cut off about 4 inches in length so I'm back above bra strap again and I'm sort of starting over, but I'm still a lot farther along then I was at this time last year.
Now that I know I can do it, I know what it takes to get there, and I know exactly how long it takes, I'm not apprehensive about cutting anymore!!
HTA,
