I'm an emotional eater too. My triggers for it are being anxious or bored, though.
I am a lot bigger than you, based on your description of what you need to lose, and my family is the same way about how I'll never find anyone. 30 was really hard for me too to still be alone. Now I'm almost 42 and I don't care.

I think it's a pretty common developmental stage for women to hit that age and reassess their lives.
I don't know how to stop the emotional eating or I would be a lot thinner myself

-- maybe just try another form of distraction, I guess. I'm too lazy to get out of the house and take a walk, but I hear it works.

Good luck.
