I came to say three things. 1. As a female, I know that once I know someone’s personality, they can literally become more attractive. It’s weird, i know they may not be conventionally attractive but they become physically attractive because of who they are. So, though I understand your self doubt, just know she very likely doesn’t see herself as “settling” but really does love/like you. 2. If you want to improve yourself, you can :) I think that exercise, reducing sugar intake, and doing intermittent fasting (16:8 look it up online) could be really beneficial, not for the weight loss (although that’s a likely effect) but for the huge confidence boost you’ll get. Exercise makes u feel hecka great. 3. I feel you I have low self esteem too. I’m trying to improve myself, for myself. I’m rooting for you!
