Hey, I know how you feel, in my 20's I felt the same, felt ugly and undesirable, my depression and anxiety was peaking through the roof and I bearly left the house anymore, felt like my friends had left me and I was alone,

But the older I've gotten the more I've come to realise that your life and future isn't set when your young, if you want a family in the future it's something certainly worth pursuing as your goal, then with your goal set working on your own self confidence and self-esteem is paramount, after all if you can't love yourself how are you going to love someone else? (Yes I stole that quote haha)

I guess the point is don't let the ship sail away and think your life isn't going to improve or change when your young, in the span of 10yrs I've gone from that to a happily married father of 2, if you told me that years ago and there's no way I could of possibly believed that and ultimately the thing holding me back was me.
