You've lost 160Ibs which is great. Why do you feel you aren't a capable of losing more? You've already proven to yourself you're capable of losing weight, of course you can lose more. But, be sensible about it, don't starve yourself. Eat healthy and continue to do what you did to lose those 160Ibs to lose even more weight. Until you're happy with how you look.

The truth of the matter is, that if you want to look desireable to men and you really want to attract men you have to change. That doesn't mean you completely change who you are, but you have to compromise a bit. Perhaps instead of going in a dress, you wear some nice jeans, a t-shirt and some make up? And once, perhaps a new haircut. When you go out with friends don't look or think about getting attention from men. Think about enjoying the moment you're out with friends. Look up on body language and try and practice those things to make you look less defensive. Men aren't as good as reading body language as woman, but many men can pick up on a woman who comes across as overly defensive, and since many men are afraid of being rejected, why should they ask you out? When they know full you aren't interested.

But the biggest you have, is that part of you is afraid of wanting attention from men. You need to get that sorted out with your therapist.
