Body changes, muscle gain

Dear community. Grateful to be with fitnessblender since several years. Since I started my journey with fb,my goals, body and attitude have changed towards a healthier lifestyle. I do however struggle with some of the changes my body is going through. I have gained muscles and therefore size: from quite petit to a "muscular-two-sizes-up". I am strong and healthy but it feels a bit overwhelming to be bursting out of all my summer clothes from last year. How do you guys deal with these shifts? Yes, I did buy a new dress :) but on a emotional note I seem to be stuck with the old annoying desire to be thin. I am being a bit embarrassed to post this but would love to hear from you. Anyone had to loose the skinny girl to discover the strong one? And did you immediately like her?
