I had my surgery 6/25 too! And let me tell you I regret it most days. I know that’s probably not the positive reply you wanted to hear but it’s real. I think being depressed for a little while is common after the surgery. If you think about it you’re trying to change a lifetime of habits very quickly and it’s a shock to the system. I haven’t lost anywhere close to the weight you have (only 20lbs) and you can’t tell which is super frustrating.
With that being said tho it takes time to adjust (I’m hoping). Both my sister and father had the surgery and they are both happy. Keep your head you, you definitely aren’t alone in the struggle.
