You don't have to explain the sheer despair of depression, everyone here gets that. It does help to talk, properly, about how you're feeling, however. In my 20's, most of my friends were work friends - and transitional at best. My true 'circle of friends' have been built up through my 30s - and they're the ones I trust completely. It's from that age onwards that we learn what is really important in friendship. So don't fret.
I don't think think I've ever discounted a man because of his height, build, looks. What has always mattered to me is personality, kindness, and someone who can make me laugh. It's doesn't matter how tall the man is who's rushing you to A&E after a fall, just that they're prepared to be the one to get you there.
