I know this must be a very difficult time for you but don’t worry I’m sure you will work it out.
Anyway, judging by your words you must be literally up-to-ears in work. I definitely think that you should talk to your boss and take a day off. Have a break and get away from it all. Go in the mountain for example, you know, get some fresh air. On the next day you will feel like reborn and the work will seem less.
If I were you, I would think really seriously about the quarrel with Helen. I must admit the guilty one is you. I can see that you really like that woman so you’d better go ahead and apologize to her. I think that a bunch of flowers and some red wine should break the ice.
Come on, buck up, I’m sure these bad times will pass very fast.
