I feel you, honey. I can't wait to feel confident to wear skirts and dresses and anything that reveals even a hint of skin. Now that summer is here, I've been feeling very dysphoric with the swimsuit issue. I need to keep reminding myself that all cis women deal with their own issues of confidence, appearance, comparison, longing, etc.
I realize that there may be a different sense for you because of visibility (I don't know where you are at with being open or out), but know that the feelings of insecurity is actually a trademark of being a woman!
