I totally know this feeling
have you ever looked at what body shape you are? There are some good websites that help you find what clothes enhance your figure and make you look slimmer.
Definitely stick to what you're comfortable with if that's not feasible, but I promise as you lose weight it will get better. I know I never believed that back when I started, but even though I still have so long to go, I really can't believe the difference in my confidence
Keep going hun, we're all here to cheer you on!!
