Wedding dress shopping anxiety

Hi everyone! I'm going to be wedding dress shopping this month and I am so so scared. I'm obviosuly also very excited, but I have body image issues and I feel super nervous that I'll look ugly in everything I try on, or that I won't be able to find anything in my size that looks good on me. I'm 5'3 and weigh around 160lbs, but I used to be at around 130, and I haven't come to terms with my body now. (I gained weigh due to depression over eating). Am I being crazy?? :(
