embarrassed by my weight gain

I feel embarrassed being seen sometimes because of how big I've gotten... its not because I'm stuffing my face either I have a hormonal imbalance which is supposedly one of the reasons why I've gained so much Weight a little over 30 lbs it looks like ive gained more but im only 5'1 so yeah theres only some room all that could go to... just this past weekend I saw someone I hadn't seen since I got pregnant & she said "wow you've put on alot of weight specially in your face" it made me feel like complete shit since I actually felt "cute" that day I even dressed up... Im so depressed right now I don't know what to do ... tips anyone?
