I've gotten better at dealing with constructive criticism, I have trouble when I am criticized and it's in accurate. I get defensive and I can go from being super happy and energetic to being sad and unmotivated in seconds. It seems to suck the life out of me and then I turn into a bitch.
The other thing, is many times it isn't intentionally hurtful. I just perceive it that way. Why? Uuuughhh!
