Hey there. I'm new too, but I know a lot about needing to love myself. That's why I'm here & wanting to lose weight. I'm sort of your inverse (a guy I like asked me out a few months ago and I said no due to crappy self esteem).
I think the major thing is *wanting* to fix that. Identify your good points. We all have them. Maybe yours is how completely you love others. Maybe you've got fantastic hair or eyes or perfect skin tone or you're the nicest person on the planet. I think mine is my sense of humor. Whatever it is, work it. And take pride in it.
No one dates someone for a year without thinking that they're amazing. So I'm pretty sure that you are, at whatever weight.
