Welcome back We've all been in that position and it's not nice, it's even worse if you arent sure when the next time you are going is - which is one of the reasons why I book 2 or 3 flights in advance, so that at least when I leave I know exactly when I will return.
It's easy to say it will get better, but it does, the days turn into weeks and the weeks into months, and before you know it, it's time to get back on the plane again.
Keep in regular contact with your mahal, and don't feel too sorry for yourself. Life goes on, and no one wants to know a miserable person.
We're all friends with similar experiences on here, feel free to get your feelings off your chest amongst friends who understand.
