Having a hard time with people having faith in me after surgery. Anyone else?

Since my surgery I've lost friends because they dodnt agree with my choice.

My dad seems to like to knit pick at me every bite I take around him. It's good but kind of sad. I'm almost 30.

Today I had a coworker tell me about his wife's friend who had the surgery and is back to their normal eating habits. Maybe he mentioned it because he wants me to succeed.

I've been struggling with my emotions recently and I am not sure if it's lack of protein or nutrients. I want to be successful with this surgery so bad. Im almost down 70lbs in just about 3 months.
