I have been dating a girl for 4 months who lives 5 hours away from me and we never met. I'm scared to meet.?

Basically, I live in New Jersey and I have been dating a girl whom I met through a friend of mine that moved to New Hampshire. We have sent pictures and we talk all the time over the phone and texting. We have discussed meeting but I don't feel confident in my appearance to be with her. I am overweight (obese) but she says I look handsome. I already know I don't, even though she says it. I feel like I would embarrass her if we met because of how beautiful she looks and how "big" I am. I've been trying to lose weight, since we've gotten a stronger love connection, but I am hardly close to being what i want to be in order to feel comfortable around her. She wanted to meet up over the summer, possibly a month or so. My question is.. should I tell her it is too soon to meet so I can focus on my weight (she already knows that I want to lose the weight and the reasons for it) or should I meet with her and risk embarrassing myself if she no longer finds me attractive when we meet? I feel perfect with her and she feels the same way about me, unfortunately I am not comfortable enough with my appearance to meet her. Any suggestions?
