Haha. I felt happy reading this that am not d only one screwed by women. But then, the depression you mentioned alerted me. Long back when some mildly similar shyt happened, I was lucky I got travel by work. Went to London. Things got better. So if you are willing to take some advise friend. She did good by blocking you. Only thing that will heal this is distance and time. And make no mistake, it won't go away soon. Wow. Takes too much time and sadness. BUT it goes away. You will let go of her and stop caring.
Just do this dude. Try to travel. Anyways we get flexible work from home option right? I would say travel to a good place and maybe work from there for a week. Don't keep your mind idle. I mean don't take a full week off that will only be spent by crying...
So maybe travel to a place, work from there, just take 1/2 days off visit some good places. Take photos with those foreigners or ask them to take yours. Attend some useless conferences. Not sure what trends in Finance, but we had a lot of cool tech events happening in London. I used to go attend them and mingle with folks.
Bro. Forget her & fck her like this. You got to save your heart and character for the actual woman who is gonna stay with you for the rest of your life..... Hope my rant helps
But year remember distance & time
