I was going to create a new thread but this is pretty much how I feel. I can't stop crying either. I left him July 31st of 2015 after spending four months setting up our home and brought over our cat and dog. We've been together for nearly 4 years, mostly while he was living on a green card in the US.
We chat on messenger all the time, and Skype or facetime once a week. It's tough, and I cry a lot but honestly, the time has flown. This is the longest we've ever been apart but I couldn't tell you where the time has gone. I really hope the time goes by as quickly for you. the best I can say is do not wait a second longer than you have to to submit your forms and try to go priority. I didn't go priority and I severely regret it.
And about the job, I do suggest you at least look/ apply. I don't know what field you're in but I wish I could have had a job while I've been back. Unfortunately my profession wasn't easy to go back into without a huge time investment (real estate--doesn't pay off for months). If you have the means, a way to get to work (if you still have a car or public transport) it's worth trying, even if you are leaving sooner rather than later. The money will definitely help with the ever-rising costs of the visas.
