People keep telling me the same thing and it's making me very upset and irritated

Sorry this will be a little rant...

I'm currently 4 days post op, and everyone in my life keeps telling me that "you're gonna be a new man" or "you're going to change for the better" and other stuff along those lines.

It keeps irritating me and makes me upset because I don't plan on changing, I might loose weight and be moderately healthier, but doing so won't change who I am. I'm still going to have the same ideals and opinions, I'm still going to enjoy the things I enjoy.

I know it's just a phrase but it's really annoying hearing how people are expecting such a large change to happen like I'm going to a completely different person. I'm happy the way I was before the surgery. I only did this for my own health and a promise I made to a dead friend.

It could also be the post surgery depression that my surgeon told me about but still I feel like I can't speak up when they say this stuff cause I don't want my family and friends to be disappointed in me.
