I'm 19, 5'5, 225lbs. Considering gastric bypass. Terrified of needles & my boyfriend will be against the surgery?

Boyfriend feels this surgery is a shortcut. He does not think I'm overweight enough to even be considering surgery. Both my parents have had this surgery(and kept the weight off.) I know this is an option for me but I'm afraid of the pain(of NEEDLES/of after surgery pain.) Also not sure how to tell my boyfriend I'm going to be getting this surgery without feeling like he's judging me and thinks I'm fat and lazy. It's so embarrassing and I just don't know how to even bring it up or if I should.
