Single/weight issues

Maudlss
Hey guys, Recently for the past couple of weeks I've been feeling really depressed which has caused me to eat so much unhealthy foods and keep myself locked up in my bedrooms after long days at work. 
My life is like a never ending circle.. go to work and then come home sleep eat repeat. Day in and day out. I'm 20 years old and I'm single and I've been feeling pretty lonely for a while. Most of my friends are in committed relationships and I've been  feeling like the ugly duckling recently. I know I'm still young and have my whole life ahead of me but I can't but think that maybe if I just lost a bit of weight or something somebody might take a bit of interest in me. And I know that's awful to say as looks aren't everything but I wouldn't go for a guy who was a tad overweight so I suppose that's why I'm not getting attention from the opposite sex? I dunno.. I even downloaded tinder! Which was a complete and utter fail. So many guys were asking me for sex and would block me when they realised that I wasn't interested.
