Body Image

So, I have always had serious body image issues. I wanted this pregnancy and baby so badly and I am incredibly excited. However, I feel like I just can't get excited about my growing body. While everyone is super excited about their bumps, I am super apprehensive about getting bigger. I am 5'5 and I weighed 125 when I found out. At 19 weeks I was 136 this morning. I know that this is within the healthy range, but I am having a hard time looking at myself in the mirror. I have struggled with eating disorders in the past, but I would never do anything harmful to my body while I have this precious life depending on me. I am also very nervous about how I will feel/look post-partum.  I was just curious to see if this was something that anyone else is dealing with or to see if anyone had any advice on how to get past this and enjoy the changes that are taking place. Please no negative comments.
