Without reading all 70 answers all I can say is why worry? My ex walked out on me 7 years ago tomorrow, my Grand mother (now deceased) was in hospital with pneumonia, I'd just gotten over the flu (and it was flu!) and was only weeks away from my birthday.
All because her mother did'nt want her daughter with a Gualau.
It was a tough time, but all you can do in any situation is keep going.
Stay true to yourself, do the things you enjoy, be open and engaging with company, force yourself to go out (if need be).
But above all else keep going and you'll end up somewhere.
To fall in love you have to accept (and embrace?) the fact you may end up looking the fool but you have to be open to recieve it.
The only other option is to give up, I kept going and won through, but I'd still sooner be single than with someone I don't love or who does'nt make me happy. I know loads of people who stay together because they're afraid of being single.
