I went through the same thing as you at first.   Many years after my divorce and still dealing with low self esteem from it, I suddenly found out that I had a genetic disease that caused me to be overweight.  When I found out the cause and the cure, I lost over 70 lbs. in a fairly short time frame.  I have literally had people who have known me for years run into me in the grocery store and have a hard time recognizing me because I was so overweight for so long.  All I can say is that as time goes on, I am less suspicious of men being interested as I realized there are guys out there that like women that do not fit the “ideal”.  I am still not thin by any means and will always be considered curvy due to my build.  I believe voluptuous is the term which I know is not the ideal in our society.  However, that being said, what really counts is how you feel about yourself and to heck with every one else!  Not only that but I have ran into many guys that actually don’t like “twigs”.  I think I realized this when I had some  younger guys hit on me in front of my daughter and she informed me I was a cougar…of course I had to explain to here I wasn’t since they were just flirting.  I know better than anyone how much damage being overweight  can do to a person’s self esteem even long after the weight is lost.  If nothing else due to my special diet to stay healthy I have learned that if a man can’t accept me for who I am then I don’t need him. Granted it took a guy splitting on me (first boyfriend after years of being divorced… devastated me) and a few being interested despite my disease which I am upfront and unapologetic about (flattering) to make this really hit home.  Basically, any man who is worth it will accept you in all your phases and love you.  The current guy I am involved with recently saw my fat pictures and knows about my condition and even before he saw them was continually asking me question to try to understand what I deal with.  While this has limited the amount of dates when I was looking, it also weeded out the fluff.  

Congratulations for your achievement.  In terms of the emotions that you are experiencing they are real to you and you are entitled to what ever you feel.  No one knows exactly what you feel because no one is you.  Take as long as you need to work through your emotions, try not to beat yourself up for feeling the way you do because you are entitled.  What you could do to is give yourself a time frame and work to it.  Meet with a counsellor if you need to, repeat affirmations, and work on feeling happy and content with you, and accept any and all emotions and feelings you experience.  The next time a man comes up to you and hits on you say thanks!  If your upset thats ok.  But set yourself a goal and say the next time a man hits on me im respond in a certain way and im not going to get upset.  After a while of persistent effort you will probably start to respond in a different way.  All I can say is you go girl!!!     

By the way, most of us become fat not because of emotional issues but because we all eat too many carbohydrates… There is nothing wrong with us..it’s just the food, which is easy to change.
