Self Love

So I suffer from really low self esteem. I have been overweight my whole life. I’m getting bariatric surgery in a few months for a healthier lifestyle. I’m very excited for it! However, I’ve never been in a relationship. I’m kind of scared, and sad that after this surgery, after losing weight, if someone is interested in me or wants to start a relationship with me I’ll think it’s only because I’ve lost weight. I don’t know what I can do to help myself not see things that way.
