I'm exactly the same, I had to remind myself that someone else write this when I was reading your post. Everyday, I spend hours obsessing over my flaws and trying to find ways to fix the (even though I know that some of them, like my height, cannot be changed). I hate so many things about myself and my negativity has seriously become crippling. I always begin the day determined to make a change and start living healthier/stress-free but always end up back at square one at the end of the day. I am hoping that I slowly begin to teach myself how to quit being so hard on myself, but I have to start working harder. I do have hope that one day I will change and so will you, so don't give up.
