E.S.
H. - you started off by saying that you are having odd moments lately where you lose control. It may not be that Julia is hurting herself solely to express her frustration, but because she's picking up on your tenseness. You need to find a way of letting go whatever is bothering you enough to make you lose control because it is GUARANTEED she is picking up on your insecurity, tension, anxiety, etc. That's too much for her to handle. Whether you feel like it or not, your job, most of the time, is to be confident and self-assured. When you are not, neither will she be. You have to believe that you are doing your best and that your best is enough.
