Lost 77lbs

So I've always been a heavier person, my highest weight was 235 over the last 9 months I've lost 77lbs. and I just found out last Thursday that I am pregnant 💓 I'm super excited but I also get very depressed because I feel like I worked so hard to get here and I just don't want to gain all my weight back and feel insecure about my body. I feel like a bad mom already because I'm being so selfish..
