I'm dreading one of my childhood friends getting married because I've gained a bunch of weight
Are you scared that they will be mad about your weight gain?
No, but I haven't seen them since I gained the weight and I'm upset about it.
I don't think there's any reason for you to be embarrassed about your weight. Your friends won't care, they'll just be happy that you're at their wedding. I think you should try to be more confident in yourself.
I can be confident in myself. I'm looking forward to the wedding.
Good, that is what I like to hear! You should never feel bad about gaining weight, and never let anyone get you down about how you look.
