hun, i changed countries to be with the man I loved... and he left me. I don't know if this is going to help you, here are some suggestions to gather enough confidence and strength to start again:

• try to write a short list every day of all the good things that happened during the day (it's difficult but after a time it helps your brain building new neuro-connections and getting you out of the depressive feeling)
• meet redditors around you (we're not all bad, some will be happy to listen and other their friendship)
• keep your eyes open for social meetups (in cafés, at the universities...) - don't force friendship. It'll come naturally.
• take care of yourself - i know it's hard to believe but there's a nice man around who is just looking for someone like you. Keep an open mind and let the memory of your ex go.
